Clinical Information

This test uses the simple screening technique that involves immunoassay testing for drugs by class. All positive immunoassay screening results can be confirmed by gas chromatography mass spectrometry or liquid chromatography tandem mass spectrometry and quantitated if applicable.

 

This assay was designed to test for the following:

-Barbiturates

-Cocaine

-Carboxy-tetrahydrocannabinol

Reference Values
