Lab technician inspects throat culture Lab Tests Online has been designed to help you, as a patient or family caregiver, to better understand the many clinical laboratory tests that are part of healthcare today as well as the diagnosis and treatment of a broad range of conditions and diseases. At a time when patients have been granted greater access to their personal medical information through electronic health records and lab reports, Lab Tests Online fulfills a vital need for medical laboratory information that is easy to read and understand. The site is a go-to reference for your questions ranging from why a lab test is ordered to what the results might mean.

Laboratory medicine has long been an unseen aspect of healthcare but has been coming more to the forefront as patients are asked to become more active partners and to make informed decisions about their care. Lab tests often provide an important link between the patient's presentation of symptoms and the subsequent diagnosis and treatment of a particular condition or disease. Lab Tests Online aims to provide a greater understanding of information gained through lab tests so that you can talk to your healthcare provider and make thoughtful decisions about your care.

Laboratory testing technology has also made great strides in the ability to detect disease and help guide treatment decisions. With this progress, however, lab testing has become more complex and specialized. If you are a medical professional, Lab Tests Online can serve as a quick reference tool or as a resource for keeping up with advances in laboratory science. The information contained here can facilitate consultations between health practitioners and the laboratory professionals who provide the lab services.
