Cannabinoids (THC), Qualitative Urine Drug Abuse Screen

Mnemonic:    [U THC Ql]
Name:    Cannabinoids (THC), Qualitative Urine Drug Abuse Screen
Specimen:    10 mL urine from a random collection.
Minimum Spec:    5 mL
Neonatal Spec:    1 mL
Transport Temp:    Refrigerated
Spec Stability:    Stable 5 days refrigerated.
Reference Range:    Negative
  Method:    Enzyme Multiplied Immunoassay Technique (EMIT)
Note:    The VITROS Cannabinoid assay detects 11-nor-Delta 9-THC-9-carboxylic acid, the major metabolite of delta 9-THC in human urine. It also detects other delta 9-THC metabolites. Marinol, a synthetic hydrocannabinol, also is metabolized into 11-nor- delta 9-THC-9-carboxylic acid, and can be detected by this assay.

This assay uses a threshold concentration of 50 ng/mL to separate a negative result from a presumptive positive result.

Confirmation testing will be performed upon physician request.

This test is indicated for medical purposes only.
