Methodology
Enzyme Immunoassay (EIA)
Screens for the following drug classes: amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, fentanyl, methadone, methamphetamine, opiates, oxycodone, phencyclidine, propoxyphene, and tricyclic antidepressant.
Reporting
Reference Range:
Not detected
Reflex testing: Confirmatory testing is forwarded to Mayo Laboratories when drug screen is order with confirmation.
Interpretive Data:
Positive results are unconfirmed and may be used for medical treatment only, not for employment or legal purposes. Testing performed by immunoassay.
