DRUGS OF ABUSE IN URINE (DAU) SCREEN

Laboratory: Drug Testing

Test Description: The Division of Consolidated Laboratory Services (DCLS) performs routine drug and alcohol testing on urine for the Department of Corrections in the state of Virginia, using the Emit II Plus and Immunalysis assays. These assays are used for drugs of abuse screening. A more specific, alternative chemical method (mass spectrometry) must be used to obtain a confirmed analytical result. Clinical consideration and professional judgment should be applied to any drugs-of-abuse test result, particularly when preliminary positive results are reported.
