If your employee or prospective employee produces a non-negative result, you’ll need verification from a lab. In fact, several states require lab confirmation.
Instant drug testing products provide only preliminary analytical test results. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS or LC/MS/MC) is the preferred confirmatory method, according to the Substance Abuse and Mental Health Services Administration (SAMHSA). Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used, because every specimen is a potential source for legal action.
