Test Details
Methodology
Initial presumptive testing by immunoassay at the following testing thresholds: alcohol biomarkers (ETG/ETS), 100 ng/gm; amphetamines, 100 ng/gm; barbiturates, 100 ng/gm; benzodiazepines, 100 ng/gm; buprenorphine, 5 ng/gm; cocaine and metabolites, 50 ng/gm; fentanyl, 2 ng/gm; methadone, 50 ng/gm; opiates, 50 ng/gm; oxycodones, 50 ng/gm; phencyclidine (PCP), 25 ng/gm; tetrahydrocannabinol (THC), 25 ng/gm; tramadol, 50 ng/gm; presumptive positives confirmed by definitive chromatography mass spectrometry (GC/MS or LC/MS-MS).
Result Turnaround Time
3 - 6 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
