Test ID: DAU9    
Drugs of Abuse Screen, DAU9, Urine

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

Testing begins with screening tests for drugs of abuse. Positives are confirmed and quantitated by definitive methods. Gas chromatography-mass spectrometry for amphetamines, barbiturates, benzodiazepines, cocaine and metabolites, phencyclidine, and tetrahydrocannabinol metabolite at additional charge. Methadone and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry at an additional charge.

Specimen Type Describes the specimen type needed for testing

Urine

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Container/Tube: Plastic, 60-mL urine container (Supply T313)

Specimen Volume: 30 mL

Collection Instructions:

1. Collect a random urine specimen.

2. No preservative.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
