Benzodiazepines, Urine, Quantitative
Also known as: CDCO BENZO
Use
This test is used to obtain quantitative results for benzodiazepines in urine, particularly useful for follow-up on a presumptive result. It helps identify specific drugs taken by a specimen donor, though interpretation must account for common metabolites that may also be prescription drugs.
Special Instructions
For general screening, the preferred test is 'Benzodiazepines Urine Screen with Reflex to Quantitation (2012225)'. It requires random urine collection and involves transferring 0.5 mL of urine without additives to an ARUP standard transport tube. Unacceptable specimens include those exposed to repeated freeze/thaw cycles.
Limitations
This test is for medical purposes only and is not valid for forensic use. Identification of specific drugs is complicated by common metabolites. Absence of expected drugs may indicate noncompliance or issues like poor drug absorption. Limitations include potential interference from diluted or adulterated urine and test constraints.
