What Are Drug Test Cutoffs?
Drug test cutoffs are the minimum concentration levels at which a drug or its metabolite must be detected in a sample (urine, saliva, hair, etc.) to report the test as positive. These thresholds ensure that the results are accurate and reduce the chances of false positives caused by trace levels of substances. For instance, if the cutoff for THC (from marijuana) is 50 ng/mL in a 5-panel or 10-panel drug test, any reading below this level would be considered negative.
Cutoffs vary depending on the type of drug test being conducted (e.g., DOT vs. Non-DOT), the testing method (urine, oral fluid, or hair), and compliance requirements.
Why Are Drug Test Cutoffs Important?
- Accuracy – Cutoffs help distinguish between genuine drug use and environmental exposure, providing credible results employers can trust.
- Compliance – Federal agencies like the DOT enforce strict cutoff guidelines for regulated drug tests. Ignoring these can result in hefty penalties.
- Fairness – Clearly defined cutoffs create consistency, protecting employees and employers from potentially unfair outcomes.
- Safety – By identifying drug use at levels above the cutoff, you help maintain a drug-free workplace, minimizing potential accidents and productivity losses.
What Are the DOT-5 Drug Screen Cutoffs?
DOT-regulated drug tests use a standardized 5-panel drug screen to test for the most commonly abused substances:
- Marijuana (THC Metabolites) – Cutoff for initial test is 50 ng/mL; confirmatory test is 15 ng/mL.
- Cocaine Metabolites – Initial cutoff is 150 ng/mL; confirmatory test is 100 ng/mL.
- Amphetamines – Includes methamphetamine and MDMA (Ecstasy). Initial cutoff is 500 ng/mL; confirmatory test is 250 ng/mL.
- Opiates – Includes morphine, codeine, and heroin. Initial cutoff is 2,000 ng/mL; confirmatory test varies, but heroin’s marker is 10 ng/mL. Oxycodone 100n g/ml for initial cutoff and 100 ng/ml for confirmation. Other synthetic opiates 300n g/ml for initial cutoff and 300 ng/ml for confirmation.
- Phencyclidine (PCP) – Cutoff is 25 ng/mL for initial and 25ng/mL for confirmatory testing.
These standardized cutoffs are essential for regulated drug tests under DOT guidelines.
Regulated Drug Test vs. Non Regulated Drug Tests
What Is a Regulated Drug Test?
A regulated drug test falls under federal guidelines, such as those managed by the DOT or FMCSA. These tests are mandatory for safety-sensitive positions, such as truck drivers, airline pilots, or railroad employees. They include:
- 5-panel drug tests
- Adherence to strict chain-of-custody documentation
- Oversight by a Medical Review Officer (MRO) to ensure accuracy and confidentiality
- Compliance with the FMCSA Drug and Alcohol Clearinghouse for reporting results for all FMCSA Employers.
What Is a Non Regulated Drug Test?
A non regulated drug test, often called a Non-DOT Drug Test, is not mandated by federal agencies. These tests allow employers greater flexibility to create policies tailored to their workplace. Employers may choose customized panels, such as a 10-panel drug test, to screen for additional substances like synthetic opioids, Tramadol, Fentanyl, Buprenorphine or synthetic marijuana (K2 Spice).
Non regulated tests are ideal for industries like retail, construction, or car dealerships, where federal rules don’t apply but maintaining a drug-free environment is critical.
Common Uses of Non-DOT Drug Tests:
- Pre-employment screening
- Random testing through a Random Testing Consortium
- Post-accident investigations
- Return-to-duty or follow-up testing (after a failed drug test)
Additional Testing Methods
Employers can also opt for specific methods based on their requirements:
- Hair Follicle Drug Tests – Detects usage for up to 90 days.
- Oral Fluid Drug Tests – Picks up recent drug use.
- Instant Drug Tests – Provides rapid results, often within minutes.
Random Testing: A Key Pillar of Workplace Safety
Random drug testing creates a proactive approach to workplace safety. Various federal and industry-specific random testing consortiums—like the FMCSA Random Consortium or the FAA Random Testing Consortium—conduct tests without prior notice. Employers in regulated industries must ensure compliance with random testing policies.
Workplace Screening Intelligence also offers consortia for non-regulated employers, such as the Ohio BWC 5% Random Testing Consortium, supporting your workplace regardless of industry.
What Random Testing Programs Do You Offer?
Standalone Random Drug Testing Programs
DOT Consortiums:
FAA Random Drug Testing Consortium, FMCSA Random Drug Testing Consortium, FRA Random Drug Testing Consortium, FTA Random Drug Testing Consortium, PHMSA Random Drug Testing Consortium, and US Coast Guard Random Drug Testing Consortium.
NON-DOT Consortiums:
CAPUC Random Drug Testing Consortium, NON-DOT Random Drug Testing Consortium, OHIO BWC 5% Random Drug Testing Consortium, OHIO BWC 15% Random Drug Testing Consortium.
Physicals and Drug Testing Go Hand-in-Hand
Employers often pair drug testing with physical exams to ensure workers meet job-specific health standards.
- DOT Physical Exam – A comprehensive check required for drivers in safety-sensitive roles to obtain a valid DOT Medical Card.
- Non DOT Physical – Tailored to meet the health requirements of non-regulated roles.
Workplace Screening Intelligence simplifies both processes. Need a DOT Physical near me or a Non-DOT Drug Test screen? We’ve got nationwide sites to meet your needs.

Do I have to utilize the FMCSA Drug and Alcohol Clearinghouse?
Simplifying FMCSA Clearinghouse Compliance with CTPA Services
Yes it is mandatory that all employers utilize The FMCSA Clearinghouse, developed by the Federal Motor Carrier Safety Administration (FMCSA), is a vital online database designed to promote safety within the transportation industry. It records drug and alcohol violations committed by commercial drivers, ensuring that those who break regulations are barred from safety-sensitive roles until they complete the mandated return-to-duty process. Employers are responsible for reporting violations, such as failed tests, to this system.
How to Comply with FMCSA Drug and Alcohol Clearinghouse Requirements
Here are the steps employers must take to ensure compliance with the FMCSA Clearinghouse regulations:
- Register in the FMCSA Clearinghouse to access the system and its functionalities.
- Update your DOT Drug and Alcohol Testing policy, including an FMCSA Clearinghouse addendum, to align with current regulations.
- Educate supervisors and employees about their rights and responsibilities under the FMCSA Clearinghouse rules.
- Run pre-employment queries in the FMCSA Clearinghouse for all new hires.
- Conduct annual queries on all drivers to ensure continued compliance within the system.
- Report positive alcohol tests promptly in the FMCSA Clearinghouse.
- Log and report any refusals at collection sites in the FMCSA Clearinghouse.
- Document and report all instances of drug and alcohol use as required by FMCSA regulations.
- Record return-to-duty test results in the Clearinghouse.
- Report completion of follow-up testing programs for employees returning to safety-sensitive roles after a violation.
- Medical Review Officers (MROs) must upload all positive drug test results to the FMCSA Clearinghouse.
By following these steps, employers can stay compliant with federal regulations and contribute to a safer transportation industry.
Why Choose a Consortium/Third-Party Administrator (CTPA)?
Complying with FMCSA Clearinghouse requirements can be overwhelming and time-consuming. That’s where a Consortium/Third-Party Administrator (CTPA) comes in. A CTPA, such as Workplace Screening Intelligence (WSI), can take on some or all compliance responsibilities, streamlining the process for employers. From managing annual queries to submitting reports, WSI’s FMCSA Clearinghouse Program ensures every detail of the compliance process is handled efficiently and accurately.
