A test panel is a predetermined group of medical tests used in the diagnosis and treatment of disease.
Test panels (sometimes called profiles) are typically composed of individual laboratory tests which are related in some way: by the medical condition they are intended to help diagnose (cardiac risk panel), by the specimen type (complete blood count, CBC), by the tests most frequently requested by users (comprehensive chemistry profile), by the methodology employed in the test (viral panel by polymerase chain reaction), or by the types of components included (urine drug screen).
