9-panel drug tests detect the same drug metabolites as 8-panel tests with the addition of propoxyphene, an opioid painkiller.
- A 9-panel drug test builds upon the eight main categories of drugs from an 8-panel test (marijuana, cocaine, basic opioids, phencyclidine, amphetamines, barbiturates, benzodiazepines, and methadone), plus propoxyphene.
- The 9-panel drug test is primarily used for the precise detection of propoxyphene.
- The main utility of the 9-panel drug test is usually within employment-related testing.
What is a 9-panel drug test?
A 9-panel drug test is an expanded drug screen panel that includes an additional opioid pain reliever, propoxyphene.
9-panel drug tests are less frequently used than 8 or 10-panel tests and is often only used for the precise detection of propoxyphene or if it is an organization's preferred method of testing

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:[2]
- Pre-employment: Some employers will ask prospective applicants to test for drug use, 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 use.
- Post-accident: A drug test may be required after a workplace accident to determine whether substances were involved, though it may not definitively prove it depending on the timing and detection windows.
- 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.
