When is a 9-panel drug test used?
A 9-panel drug test is most frequently used by employers to test for drug use in employees and prospective candidates. Scenarios employers may use a 9-panel drug test include:
Pre-employment: Some employers will ask prospective applicants to test for drug abuse, often after a provisional offer of employment has been given.
Suspicion of drug use: Employers may ask employees to take a drug test if they show symptoms of drug abuse.
Post-accident: A drug test may be required after a workplace accident to determine whether substances were involved, though it cannot definitively prove it.
Random/Periodic screening: Some employers will use random or scheduled drug tests to monitor drug use. This will often be clearly outlined in their drug policy guidance.
Return-to-work: An employer may ask for a drug test to be performed after an extended absence from work, especially if the employee has been away for drug abuse treatment.
9-panel drug tests are rarely used in other areas like sports or legal testing but may be used in medical settings. Read here to learn more about the drug test process.
