Barbiturates (500mL) - 5423 tests

The DRI Barbiturate Assay is intended for the qualitative and semiquantitative determination of barbiturates in human urine. This assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method.1,2 Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
