Accordion Title
  • Code of Conduct

    AACC has designed Lab Tests Online to comply with the eight principles of the Health On the Net (HON) Code of Conduct for medical and health web sites. The HON code logo at the bottom of each page reflects a commitment to providing credible medical information. Click on the HONcode logo to learn more.

    The HON Code of Conduct lists the following principles:

    1. Authority: Any medical or health advice provided and hosted on this site will only be given by medically trained and qualified professionals unless a clear statement is made that a piece of advice offered is from a non-medically qualified individual or organisation.

    Lab Tests Online: All medically-related information on the site has been culled from qualified resources. Sources used are listed at the end of each article. All test, condition, feature, screening, and news articles are reviewed and approved by the Editorial Review Board, which is comprised of highly qualified laboratory and medical professionals.

    2. Complementarity: The information provided on this site is designed to support, not replace, the relationship that exists between a patient/site visitor and his/her existing physician.

    Lab Tests Online: AACC's  primary objective is education of the public about laboratory testing in order to facilitate improved doctor-patient communication. We encourage patients and caregivers to learn as much as they can about their health care so that they can become more active partners with health care providers regarding their or their loved one's medical care. Article content often reminds patients to speak with their doctors about what they have learned here.

    3. Privacy: Confidentiality of data relating to individual patients and visitors to a medical/health Web site, including their identity, is respected by this Web site. The Web site owners undertake to honour or exceed the legal requirements of medical/health information privacy that apply in the country and state where the Web site and mirror sites are located.

    Lab Tests Online: We fully respect the confidentiality of visitors. Please review the Privacy policy for more detail. Currently we are using Google Analytics to analyze the audience of the website and improve our content. No personal information is collected from Google Analytics. For further information on the privacy policy concerning Google Analytics, please go here.

    4. Attribution: Where appropriate, information contained on this site will be supported by clear references to source data and, where possible, have specific HTML links to that data. The date when a clinical page was last modified will be clearly displayed (e.g. at the bottom of the page).

    Lab Tests Online: Because this site is designed for patients and caregivers, we have not included references to source data in the text for the sake of readability. We do list sources used at the end of each article, and we do keep records of specific references off-line. If there is a question regarding a source for a specific piece of information, please contact us.

    At the bottom of every page containing substantive content, we include the date that the page or article was last reviewed and the date it was last modified.

    5. Justifiability: Any claims relating to the benefits/performance of a specific treatment, commercial product or service will be supported by appropriate, balanced evidence in the manner outlined above in Principle 4.

    Lab Tests Online: While we may discuss laboratory tests and treatments in general terms based on currently available scientific literature, we do not advocate or promote specific commercial products or services.

    6. Transparency: The designers of this Web site will seek to provide information in the clearest possible manner and provide contact addresses for visitors that seek further information or support. The Webmaster will display his/her E-mail address clearly throughout the Web site.

    Lab Tests Online: Each page on this web site clearly indicates that the American Association for Clinical Chemistry (AACC) owns the copyright and is the site producer. Sponsors and partners are presented on the home page as well as on the Sponsors and Partners pages, with brief descriptions of each organization and a link to its web site. Other contributors to this web site are listed in the Acknowledgments section, and a list of current and past members of the Editorial Review Board is also provided. We have not provided e-mail addresses for specific individuals on this site out of respect for their privacy; however, questions to the Webmaster can be submitted using the Contact Us page.

    7. Financial disclosure: Support for this Web site will be clearly identified, including the identities of commercial and non-commercial organisations that have contributed funding, services or material for the site.

    Lab Tests Online: The primary source of funding for the site comes from corporate sponsors, who are all clearly identified on the  home page and again on the Sponsors page, which includes brief descriptions of each organization and a link to its web site. Additional funding is derived from licensing revenue, individual donations, and the generous support of AACC.

    8. Advertising policy: If advertising is a source of funding it will be clearly stated. A brief description of the advertising policy adopted by the Web site owners will be displayed on the site. Advertising and other promotional material will be presented to viewers in a manner and context that facilitates differentiation between it and the original material created by the institution operating the site.

    Lab Tests Online: Lab Tests Online uses the proceeds from advertising to help sustain the website. The advertising policy is available below, and all ads are clearly labeled as advertisements. AACC maintains a distinct separation between advertising content and editorial content.

  • Privacy Policy


    The American Association for Clinical Chemistry (“AACC”, “we”, “us” or “our”) respects the privacy of the visitors (“you” or “your”) to our Lab Tests Online website, available at https://labtestsonline.org (“Website”). This privacy policy, and as amended from time to time as posted on our website at https://labtestsonline.org/policies (“Privacy Policy”) describes the types of information we may collect from you or that you may provide when you visit or use our Website or the content provided therein, or use our services related to providing information and resources for specific lab tests and testing topics (“Services”), and our practices for collecting, using, maintaining, protecting and disclosing that information. This Privacy Policy applies to the data collected by us from your visiting or use of the Website, or by those working on our behalf, through information you enter or from the data imported from authorized and approved sources. It does not apply to data collected through other websites, or by products or services not approved by us.

    Our Privacy Policy describes:

    • How and why we collect your Personal Information;
    • How your Personal Information is used and protected;
    • When and with whom we share your Personal Information; and
    • What choices you can make about how we collect, use, and share your Personal Information.
    • How we store, use, transfer, and retain your Personal Information.

    If you are a resident of or subject to data privacy laws or regulations of a country outside of the United States, please see the additional provisions at the end of this Privacy Policy.

    Below in this section are some of the highlights of the Privacy Policy. Please read this entire document for a full description of our policies.


    The following presents highlights of our Privacy Policy. The details follow this section.

                Personal Information

    We collect your Personal Information for various purposes, such as, but not limited to, corresponding with you to contact you with a response to your questions or comments, to follow up with questions of our own, and other purposes.

    We may combine the information we collect from you with information obtained from other sources to help us improve its overall accuracy and completeness, and to help us improve our business and better tailor our interactions with you.

    We may also collect information relating to your use of our Website through the use of various technologies, including cookies.

                Your Choices

    You may opt out from receiving emails from us by contacting us at [email protected], Attn: Opt Out/Info Change. You may turn off cookies in your browser. Residents or citizen of a European country have certain rights and choices, as discussed below.

                Contacting Us

    You may contact us using the Contact Information provided at the end of this Privacy Policy.

    Acknowledgement and Consent

    By using or accessing our Website in any manner, you acknowledge that you accept the practices and policies described in this Privacy Policy (and as updated from time to time), and you hereby consent that we may collect, use, and share your information as described herein. If you do not agree with our policies and practices, your choice is not to use our Website. Your use of the Website is at all times subject to our Terms of Use (available at https://labtestsonline.org/terms-of-use (the “Terms”), which incorporates this Privacy Policy. Any capitalized terms we use in this Privacy Policy without defining them have the definitions given to them in the Terms.


    What Does This Privacy Policy Cover?

    This Privacy Policy covers our treatment of personally identifiable information. This is information which may be connected to you specifically as the individual to whom the information relates. Such information may include name, mailing address, email address, telephone number, or any other information defined as personally identifiable information (or similar term) by applicable law (“Personal Information”). If you are a European citizen or resident, the definition under the GDPR regulation is different, so, please see the section toward the end of this Privacy Policy. Personal Information does not include your personally identifiable information that has been deidentified, pseudonymized, anonymized, aggregated and/or otherwise processed so as to be unidentifiable in such a way that the data can no longer be attributed to a specific individual (by reasonable means) without the use of additional information, and where such additional information is kept separate and under adequate security to prevent unauthorized re-identification of a specific individual such that one could not, using reasonable efforts, link such information back to a specific individual (the foregoing in this sentence being referred to as “De-Identified Personal Information”).

    We may also collect Personal Information from you through means other than our Website. It may also include emails, text messages, or other electronic communications, that you send to us separate from our Website, or by way of our third party service providers. This Privacy Policy does not apply to Personal Information that you provide to us through means other than our Website. However, if we combine the Personal Information we collect from you outside of our Website with Personal Information that is collected through our Website or by another means as described above, the Privacy Policy will apply to the combined information, unless specifically disclosed otherwise.

    Other than as stated herein, this Privacy Policy does not apply to information collected by any third party (including our affiliates and subsidiaries), including through any application or content (including advertising) that may link to or be accessible from or on our Website. We are not responsible for the practices of sites linked to from the Services, and before interacting with any of these sites you are advised to review their rules and policies before providing them with any private information.

    Individuals under the Age of 18

    As noted in the Terms, we do not knowingly collect, solicit or maintain Personal Information from anyone under the age of 18 or knowingly allow such persons to register for our Services. If you are under 18, please do not send any Personal Information about yourself (such as your name, address, telephone number, or email address) to us. No one under age 18 should provide any Personal Information to or on the Services. In the event that we learn that we have collected Personal Information from a child under age 18 without verification of parental consent, we will use commercially reasonable efforts to delete that information from our database. Please contact us if you have any concerns.

    Changes to Our Privacy Policy

    We are constantly working to improve our Website, and we may need to change this Privacy Policy from time to time as well.

    Our current Privacy Policy will always be on our Website at www.labtestsonline.org/policies and any updates will be effective upon posting. You are responsible for periodically checking this site for updates.

    Please note that if you have opted not to receive legal notice emails from us (or you have not provided us with your email address), those legal notices will still govern your use of the Website, and you are still responsible for reading and understanding them. If you use the Website after any changes to the Privacy Policy have been posted, that means you agree to the new Privacy Policy, including all of the changes. Use of information we collect now is subject to the Privacy Policy in effect at the time such information is collected.

    Information We Collect About You and How We Collect It

    We collect several types of information from and about you.

    • Estimate our visitor size and usage patterns.
    • Store information about your preferences, allowing us to customize and improve our Website.
    • Speed up your searches.
    • Recognize you when you return to our Website.

    The technologies we use for this automatic data collection may include cookies, flash cookies, web beacons, pixel tracking, GIF and/or IP address. Each of these is discussed below.

    Cookies (or browser cookies)

    A cookie is a small file placed on the hard drive of your computer or mobile device. It may contain certain data, including, but not limited to: the name of the server that has placed it there, an identifier in the form of a unique number, and, an expiration date (some cookies only). Cookies are managed by the web browser on your computer (Internet Explorer, Firefox, Safari or Google Chrome).

    Different types of cookies which have different purposes are used on our Website.

    Essential Cookies

    These cookies are essential to allow you to browse our Website and use its functions. Without them, some of our services would not be able to work.

    Performance Cookies

    These cookies collect information on the use of our Website, such as which pages are consulted most often. This information enables us to optimize our Website and simplify browsing. Performance cookies also enable our affiliates and partners to find out whether you have accessed one of our Websites from their site and whether your visit has led to the use or purchase of a product or Service from our Website, including the references for the product or Service purchased. These cookies do not collect any information which could be used to identify you. All the information collected is aggregated, and therefore anonymous.

    Functionality Cookies

    These cookies enable our Website to remember the choices you have made when browsing. For example, we can store your geographical location in a cookie so that the Website corresponding to your area is shown. We can also remember your preferences, such as the text size, font and other customizable aspects of the Website. Functionality cookies may also be able to keep track of the products or videos consulted to avoid repetition. The information collected by these cookies cannot be used to identify you and cannot monitor your browsing activity on sites which do not belong to us.

    It is possible that you will come across third-party cookies on some pages of sites that are not under our control.

    You may refuse to accept browser cookies by activating the appropriate setting in your browser. However, if you select this setting you may be unable to access certain parts of our Website. Unless you have adjusted your browser setting so that it will refuse cookies, our system will issue cookies when you direct your browser to our Website.

    We also use cookies to implement tracking technology on our Website. This allows us to display advertising that is tailored to you on our Website which parts of our content interest you the most and which Service categories you request. This tracking uses De-Identified Personal Information data (i.e., data that cannot be identified as being specifically associated with you) and does not use your Personal Information. We will not combine this data with your other Personal Information without your express permission. At any time, you can prevent the use of cookies like this in the future (see below for how to do this). Some of our contracted vendors and affinity partners are allowed to place cookies on our Website. Those companies may also provide you with the option of preventing the use of cookies in the future. For more information, contact the relevant third-party provider.

    Flash Cookies. Certain features of our Website may use local stored objects (or Flash cookies) to collect and store information about your preferences and navigation to, from and on our Website. Flash cookies are not managed by the same browser settings as are used for browser cookies.

    Web Beacons. Pages of our Website and our emails may contain small electronic files known as web beacons (also referred to as clear gifs, pixel tags and single-pixel gifs) that permit us, for example, to count users who have visited those pages or opened an email and for other related website statistics (for example, recording the popularity of certain website content and verifying system and server integrity).

    Pixel Tracking. In addition to using Cookies, the Website may employ “pixel tracking”, a common process which may be used in connection with advertisements on other sites. Pixel tracking involves the use of pixel tags that are not visible to the user and consist of a few lines of computer code. Pixel tracking measures the effectiveness of advertisements and compiles aggregate and specific usage statistics. A “pixel tag” is an invisible tag placed on certain pages of websites that is used to track an individual user’s activity. We may access these pixel tags to identify activity and interests that may allow us to better match our goods, services, and other offers with your interests and needs. For example, if you visit our Website from an advertisement on another website, the pixel tag will allow the advertiser to track that its advertisement brought you to the Website. If you visit our Website, and we link you to another website, we may also be able to determine that you were sent to and/or transacted with a third-party website. This data is collected for use in our marketing and research.

    GIF. We may use tiny images known as clear GIFs to track behavior of users, including statistics on who opens our emails.

    IP Address. Our servers automatically record certain log file information reported from your browser when you access the Services. These server logs may include information such as which pages of the Service you visited, your internet protocol (“IP”) address, browser type, and other information on how you interact with the Services. These log files are generally deleted periodically.

    Third-Party Use of Cookies and Other Tracking Technologies

    Some content or applications, including advertisements, on the Website are served by third parties, including advertisers, ad networks and servers, content providers and application providers. First-party or third-party cookies may be used alone or in conjunction with web beacons or other tracking technologies to collect information about you when you use our Website. A first-party cookie is a cookie set by the domain name that appears in the browser address bar. A third-party cookie is a cookie set by (and on) a domain name that is not the domain name that appears in the browser address bar. It might be set as part of a side resource load (image, JS, iframe, etc. from a different hostname) or an AJAX HTTP request to a third-party server. The information that first-party and third-party cookies collect may be associated with your Personal Information or they may collect information, including Personal Information, about your online activities over time and across different websites and other online services (i.e., tracking such activities). They may use this information to provide you with interest-based (behavioral) advertising or other targeted content.

    We do not control these third parties’ tracking technologies or how they may be used. If you have any questions about an advertisement or other targeted content, you should contact the responsible provider directly.

    We use a third-party advertising company, eHealthcare Solutions (EHS), to serve ads when you visit the Website. EHS uses cookies to serve ads on the Website. The use of cookies enables EHS to serve more relevant ads to our users based on visits to the Website and other sites on the Internet. EHS may use non-identifying information about your visits to the Website and other websites in order to provide advertisements about goods and services of interest to you. If you would like more information about this practice or to opt out of having this information used by EHS, see their Preference Manager. You may also review eHealthcare Solutions’ Privacy Policy.


                Google Analytics. We use, and some of our third-party service providers may use, Google Analytics (click for link to Google’s website) or other analytics service to analyze the Website audience and to improve the content and to help us understand use of our Services. Such service providers may place their own cookies in your browser. No Personal Information is collected from Google Analytics. This Privacy Policy covers use of cookies by us only and not the use of cookies by third parties.

    Users can set preferences for how Google advertises to you using the Google Ad Settings page. Alternatively, you can opt out by visiting the Network Advertising Initiative Opt Out page or by using the Google Analytics Opt Out Browser add on.

    We or our advertising agency or other service provider may use the information we have collected from you to enable us to display advertisements to our advertisers’ target audiences. Even though we do not disclose your Personal Information for these purposes without your consent, if you click on or otherwise interact with an advertisement, the advertiser may assume that you meet its target criteria.

    How We Share Your Information

    Personal Information: 

    Broadly stated, we may disclose, rent, transfer, or sell your Personal Information, in whole or in part, with third parties for the purpose of providing or improving the Services to you, who perform services on our behalf, or for marketing purposes. We disclose Personal Information to the following types of third parties, and for the following purposes:

    • Hosting providers for the secure storage and transmission of your data
    • Database software providers for the management and tracking of your data
    • Marketing providers who send communications on our behalf regarding our products and Services
    • Technology providers who assist in the development and management of our software or our Website
    • Fulfillment and postal vendors for the fulfillment of our products and Services
    • Survey and research providers who perform studies on our behalf
    • Advertising partners, including social media providers, for the delivery of targeted advertisements

    Except as otherwise described in this Privacy Policy, we will not disclose Personal Information to any third party unless required to do so by law, court order, legal process, or subpoena, including to respond to any government or regulatory request, or if we believe that such action is necessary to (a) conform to the law, comply with legal process served on us or our affiliates, subsidiaries, contracted vendors, or affinity partners, or investigate, prevent, or take action regarding suspected or actual illegal activities; (b) to enforce our Terms (including for billing and collection purposes), take precautions against liability, to investigate and defend ourselves against any third-party claims or allegations, to assist government enforcement agencies, or to protect the security or integrity of our Website; and (c) to exercise or protect the rights, property, or personal safety of us, our users or others.

    We will attempt to notify you about these requests unless: (i) providing notice is prohibited by the legal process itself, by court order we receive, or by applicable law, or (ii) we believe that providing notice would be futile, ineffective, create a risk of injury or bodily harm to an individual or group, or create or increase a risk of fraud upon us, our users, our Website, or our Services. In instances where we comply with legal requests without notice for these reasons, we will attempt to notify that user about the request after the fact if we determine in good faith that we are no longer legally prohibited from doing so and that no risk scenarios described in this paragraph apply.

    We require that our third-party service providers only use your Personal Information as necessary to provide the requested services to us and each service provider is subject to a set of terms consistent with the applicable portions of this Privacy Policy.

    De-Identified Personal Information: We may share De-Identified Personal Information (such as anonymous usage data, referring/exit pages and URLs, IP address, platform types, number of clicks, etc.) with interested third parties to help them understand the usage patterns for certain Services.

    Your Consent to Disclosure/Transfer of Your Personal Information

For purposes of the GDPR, we will be the “data controller” of Personal Information (referred to in the GDPR as “personal data”, and which is defined differently than in this Privacy Policy) we collect through the Website, unless we collect such information on behalf of a “data controller” in which case we will be a “data processor.” This Privacy Policy does not apply to websites, applications or services that do not display or link to this Privacy Policy or that display or link to a different privacy policy. For EEA residents and citizens, to the extent any definition in this Privacy Policy conflicts with a definition under the GDPR, the GDPR definition shall control.

    If you are a European citizen or resident of the European Economic Area (“EEA”), or other regions with laws governing data collection and use that may differ from the laws in the United States, please note that we may transfer your information to a country or jurisdiction that does not have the same data protection laws as your jurisdiction. We may do so to process your information by staff operating outside the EEA who works for us or for one of our service providers.

                Your Data Rights Under GDPR

    You have the right to gain access to, object to processing of, request data portability of, and have corrected, updated, restricted, deleted, or be forgotten of the Personal Information collected about you, subject to some exceptions and conditions. You have the right to object to certain types of processing of your Personal Information. You can opt-out of certain uses of your Personal Information. For any of these, please contact us at the Contact Information above. You can find more about these rights by reading the General Data Protection Regulation, available here.

                Data Transfers

    We are headquartered in the United States. As such, we and our service providers may transfer your Personal Information to, or access it in, jurisdictions that may not provide equivalent levels of data protection as your home jurisdiction. We will take reasonable steps to ensure that your Personal Information receives an adequate level of protection in the jurisdictions in which we process it. If you are located in the EEA or Switzerland, we provide adequate protection for the transfer of Personal Information to countries outside of the EEA or Switzerland through a series of intercompany agreements based on the Standard Contractual Clauses. We may also need to transfer your information to other group companies or service providers in countries outside the EEA. This may happen if our servers or suppliers and service providers are based outside the EEA, or if you use our services and products while visiting countries outside this area.

    If you are a resident of country other than the United States, you acknowledge and consent to our collecting, transmitting, and storing your Personal Information out of the country in which you reside.

  • Editorial Policy

    AACC's aim, and that of our collaborating partners, is to create a comprehensive, accurate, and up-to-date web site to inform the public about clinical laboratory testing. The content on this site is developed and updated in accordance with established editorial policies.

    1. Science-based Content 
    Content development is based on current scientific literature and the expertise and practical experience of an Editorial Review Board (ERB) comprised of laboratory and medical professionals from the partner societies as well as Lab Tests Online staff and, as needed, experts in specific areas of laboratory medicine.

    2. Patient-Centered
    We aim to provide information that is understandable to the general public. We also strive for a balanced approach; where there are differing views and little or no consensus about testing, we present each side of the discussion so that Lab Tests Online users can be better informed when making decisions about their care.

    3. Outcomes-Driven
    The information provided on Lab Tests Online is aimed at improving patient outcomes. Improving health outcomes through laboratory medicine is achieved with the appropriate use of testing. Our content aims to arm people with the information they need to be active participants in their care and to engage their healthcare providers in informed discussions that will result in positive health outcomes.

    4. Peer-Reviewed
    All new and modified content must be reviewed and approved by members of the ERB. This applies to news items, test and condition articles, feature and screening articles, and Glossary terms. The ERB may refer some content for review by non-ERB laboratorians or medical professionals who have a particular expertise, but the ERB has final approval of the content.

    5. Limited Brand References
    We avoid the use of company or brand names in written content, except in rare instances where reference to a particular kind of test is so closely associated with a brand that use of the brand name is unavoidable. We limit links to commercial web sites. Though brand names are an integral part of sponsor acknowledgements and advertisements placed on the site, they are separated from editorial content and are clearly marked. Editorial decisions are made by the ERB and Lab Tests Online staff and are independent of funding considerations.

    6. Content Review Cycle
    We strive to review all core content on the site (test, condition, and screening articles) at least once every three years to ensure that it is current with the latest research, technology, policies and practice. From time to time, developments in the science or policy and practice related to a specific topic may require the updating of an article in advance of its three-year review date (e.g., changes in screening guidelines). Each article displays a date that the article was last reviewed; a date that the page or article was last modified is also indicated. A modification may be a minor or editorial change that is implemented ad hoc whereas a review means that the complete article was reviewed and updated as needed.

    Because laboratory science continues to evolve, in some cases quite rapidly, we require that the most current sources possible are used when preparing new articles or updating existing articles. Experts on specific topics may be consulted when the current literature is inconclusive. We strive to use peer-reviewed sources and non-commercial resources, including but not limited to journal articles, medical texts, and online health information sites, and these are documented.

    7. New Development
    Once each year, the ERB meets to prioritize the test and condition articles that will be developed and added to the site that year. Topics for feature articles may also be considered at this time, but this is not the focus of the prioritization process. Criteria that are used to help assign priorities to topics include board member recommendations, user and other stakeholder requests, frequency of user searches, and input from editors of the global network of Lab Tests Online web sites. Other considerations include whether the test has widespread acceptance in practice, relation of the test to other test and condition articles on the site, and whether the test is included as a recommended test in the guidelines of established authorities. Condition articles are developed with higher priority assigned for those that have laboratory tests associated with them, such as for screening, diagnosis, and/or management.

    8. News Story Policies
    Topics for news stories are evaluated based on specific criteria that include whether the topic is relevant to laboratory testing and the related subjects covered on the Lab Tests Online site, whether there is a public health aspect to the story, and whether the topic is receiving coverage in the popular media. Other criteria that might be considered, particularly when the story relates to a new test or advance in technology, is how soon the new test or advance will affect – or how far away it is from affecting –patient care. Like other content on Lab Tests Online, news stories strive to be non-commercial and to present a balanced coverage of the issues.

    News items and links to them from pages on the site are available for three years from the posting date. After that time, they are removed.

    9. Links to External Sites
    All links listed in Lab Tests Online articles to sites "Elsewhere on the Web" are included because the pages to which they link are contextually-relevant and considered to be from well-regarded resources. Links are periodically checked to determine if they still function and go to the relevant content.

    Under no circumstances will Lab Tests Online place a link to a web site in exchange for a link from that web site to Lab Tests Online. Anyone may suggest a link to us, but it will only be added to the site if it is determined to be relevant to Lab Tests Online users in the context of a given topic and considered to be a credible source. No links are listed on a Sources page if they were not used as sources in the development or review of a given article.

    10. User Feedback
    We take user feedback seriously. If you tell us that some part of the information on Lab Tests Online is wrong or if something is not sufficiently clear, we will review the section of content in question and take steps to modify it if the ERB agrees that the information was incorrect or unclear. Likewise, if you alert us that a link is not working, we will promptly fix it – and we appreciate you letting us know.
