Frequently Asked Questions

A 5 panel drug test is a laboratory-based drug screen that checks for five core drug classes that are commonly associated with workplace safety, policy compliance, and legal monitoring. It is one of the most frequently used drug test panels for both employment and legal situations.
A typical 5 panel drug test screens for marijuana/THC, cocaine, opiates, amphetamines/methamphetamines, and PCP. These substances are monitored because of their impact on alertness, judgment, reaction time, and overall safety.
No. Employers, legal representatives, probation officers, and private individuals can order a 5 panel drug test directly. The donor then appears at the assigned collection site with proper identification to provide the specimen.
Screening for clearly negative samples is typically completed quickly after lab processing. When a sample is not negative, additional confirmation testing is performed before a verified result is released.
