Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
Testing begins with screening tests for drugs of abuse including amphetamines, barbiturates, cocaine, phencyclidine, and tetrahydrocannabinol. Positives are confirmed and quantitated by definitive methods (gas chromatography-mass spectrometry for barbiturates, cocaine and metabolites, phencyclidine, and tetrahydrocannabinol metabolite) at an additional charge. Amphetamines that screen positive will be quantified with liquid chromatography-tandem mass spectrometry at an additional charge.
