Clinical Significance
If the barbiturate screen is ≥ 200 ng/mL, the barbiturate confirmation/quantitation by GC-MS is performed at an additional charge.
Specific gravity, pH, creatinine and oxidants will be performed and reported at no additional charge to identify potential adulteration of the urine specimen.
This test is intended for clinical monitoring and management of patients. It is not intended for non-medical use such as employment or forensic testing.
INTENDED POSITIVES:
Amobarbital (Amytal)
Butalbital (Component of Esgic, Fioricet, Fiorinal, Phrenilin)
Pentobarbital
Phenobarbital (Luminal, Solfoton)
Secobarbital (Seconal)
POSSIBLE UNINTENDED POSITIVES:
Mephobarbital (Mebaral)
Primidone (Mysoline)
Maximum Laboratory Time
3 Days
