It's one of the most common phrases you hear from your healthcare practitioner: "I just want to run a few tests."
Laboratory tests are among the most important and pervasive aspects of modern medicine. The results of clinical laboratory tests contribute to the majority of healthcare decisions. Laboratory tests provide healthcare practitioners with the information for decisions from diagnosis through therapy and determining outlook (prognosis). For some conditions, there is just no substitute for a laboratory test. For example, high cholesterol can be identified through laboratory work long before any symptoms might appear.
Healthcare practitioners rely on the laboratory for help in diagnosing any number of conditions and for managing their treatment. They trust the results that laboratories produce. But you've probably seen headlines or heard stories about patients who suffered dire consequences, such as unnecessary surgery or even death, as a result of inaccurate laboratory test results or incorrect interpretation of the results. So, a reasonable question for any patient is: should I trust my laboratory results?
The short answer is yes, you can have as much trust in these results as your healthcare practitioner does. There are many protections in place to ensure that laboratories produce reliable results. These have been instituted by federal and state government, laboratory accrediting organizations, and individual laboratories themselves to help maintain standards of quality. In addition, there are steps that you personally can take to further increase your comfort with the quality of your laboratory results, including questions that you can ask your healthcare practitioner.
