Competitive homogeneous enzyme immunoassay method using G6PDH labeling.
Reported
Stat 2 hours, routine 4 hours
Additional Information
A concentration of < 200 µg/L is considered negative by this test. A positive result is >= 200 µg/L and indicates the presence of this class of drugs. This immunoassay is only a screening test and is not definitive. Results cannot be used for medico-legal purposes.
This assay detects a number of barbiturates at varying concentrations.
False positive results may occur due to other cross reacting substances, however, positive results are NOT routinely confirmed by a second method. If confirmation of the test result is required, it is the responsibility of the physician to separately order a specific confirmatory test for the drug identified. Samples are held for 7 days. Contact laboratory at x 31667 to request confirmatory testing. Confirmatory test code BARQNT. False negative results are also possible.
Barbiturates can be detected in urine from 1 up to 14 days after use (especially for phenobarbital as it is long-acting).
