Clinical Significance
Positive test results are presumptive and not confirmed.
A “not detected” benzodiazepine result will be confirmed and quantitated if detectable by LC-MS/MS at an additional charge.
This test is intended for clinical monitoring and management of patients. It is not intended for non-medical use such as employment of forensic testing.
Specific gravity, pH, creatinine and oxidants will be performed and reported at no additional charge to identify potential adulteration of the urine specimen.
Maximum Laboratory Time
