NEW TO SPECIALTY LABORATORY TESTING?
Specialty laboratory testing includes advanced or highly targeted tests that may evaluate biomarkers, biological pathways, nutritional factors, gastrointestinal function, hormones, environmental exposures, genetics, immune patterns, and other areas not routinely included in standard laboratory panels.
However, specialty testing is not automatically necessary for every patient, and a more extensive test is not necessarily a better test. The most useful approach begins with a clear clinical question and considers whether the results are likely to meaningfully influence care.
