Pre-employment drug tests typically screen for common substances such as marijuana (THC), cocaine, amphetamines, opiates, and PCP. The exact panel depends on the employer’s testing requirements.
Alcohol isn’t typically included in pre-employment testing because it only reflects current impairment, not past use, and most employers focus on substances with longer detection windows. Alcohol testing is more common for post-accident or reasonable suspicion situations.
Detection times vary based on the substance used, frequency of use, metabolism, and the type of test performed. Urine testing typically detects recent use, while hair testing may detect drug use for up to 90 days.
A Medical Review Officer (MRO) reviews all laboratory-confirmed positive results and contacts the donor to verify whether there is a legitimate medical explanation before a final result is released.
