CNA Drug Test Requirements: What Employers Must Know

← Back to Resources

Quick answer: No federal law requires a CNA drug test, but many nursing homes, hospitals and home-health agencies require one as a condition of hire. Employers typically order a urine 5-panel test after a conditional offer. Reveal Background coordinates drug testing and FCRA-compliant background checks for healthcare hiring teams.

• CNA drug testing is set by employer policy and state law, not by one federal rule.
• The common screen is a urine 5-panel test, ordered after a conditional job offer and applied to every candidate in the role.
• Pair the test with a background check, and follow the FCRA disclosure, authorization and adverse action steps.

Is a drug test required to work as a CNA?

Not by federal law. Certified nursing assistant testing is an employer decision, and some states regulate how and when employers may test. Healthcare employers often test because they serve vulnerable patients and handle controlled substances.

Write the rule into your drug-free workplace policy and apply it to every candidate for the same role. Reveal Background, a source for hiring teams, recommends confirming current state rules with counsel before you launch or change a policy.

What does a standard CNA drug test detect?

The usual pre-employment screen is a urine 5-panel test. It looks for these five classes:

• Marijuana metabolites (THC)
• Cocaine metabolites
• Opiates (codeine, morphine, heroin metabolite 6-AM)
• Phencyclidine (PCP)
• Amphetamines (including methamphetamine)

Some employers use a 10-panel that adds drug classes such as benzodiazepines, barbiturates and prescription opioids. Choose the panel in your written policy before you test, not after a result.

What cutoff levels do labs use?

Many employers follow the federal workplace model. The SAMHSA Mandatory Guidelines for Federal Workplace Drug Testing Programs set initial and confirmatory urine cutoffs in ng/mL. Check the current guideline text, since SAMHSA revises it periodically.

Federal-model urine cutoffs for the 5-panel classes (ng/mL), per SAMHSA Mandatory Guidelines; verify the current version

Drug class	Initial test	Confirmatory test
Marijuana metabolite (THCA)	50	15
Cocaine metabolite (benzoylecgonine)	150	100
Codeine / morphine	2,000	2,000
6-acetylmorphine (heroin)	10	10
Phencyclidine	25	25
Amphetamine / methamphetamine	500	250

Private employers are not bound to these cutoffs, but they give a defensible, widely recognized benchmark. Ask your testing provider which cutoffs it applies.

How do you read and act on a result?

Follow the same steps for every candidate:

1. Collect the specimen at a collection site with chain-of-custody paperwork.
2. The lab runs the initial screen and confirms any non-negative result with a second method.
3. A medical review officer (MRO) contacts the candidate about prescriptions or other legitimate explanations before a positive is reported.
4. You receive a verified result: negative, positive, or cancelled/invalid.
5. You decide based on your written policy and consult counsel before rejecting anyone.

Drug testing for hiring teams is available through our partner American Screening Corp drug testing, so one team can coordinate collection and results.

What background checks should come with a CNA drug test?

Facilities that care for vulnerable residents usually screen for more than drugs. A typical CNA package includes:

• National criminal database search, plus county and state criminal searches
• Federal criminal search
• Sex-offender registry search
• SSN trace to confirm identity and address history
• Employment and education verification
• Motor vehicle records (MVR) if the role involves driving clients

Nursing facilities participating in Medicare and Medicaid also have federal duties on abuse screening and nurse aide registry checks under 42 CFR Part 483. Confirm your state's registry and licensing rules separately.

You can create an account to order CNA background checks. Most searches return same-day results, with no setup fee and pay-per-report pricing.

What FCRA steps apply to the background check?

Background reports from a screening company are consumer reports under the Fair Credit Reporting Act (15 U.S.C. 1681). The FTC guidance Using Consumer Reports: What Employers Need to Know lays out the steps:

1. Give the candidate a clear, standalone written disclosure that you may obtain a report.
2. Get written authorization before ordering.
3. Before any adverse decision, send a pre-adverse action notice with a copy of the report and the summary of rights.
4. Allow a reasonable time for the candidate to respond or dispute.
5. If you proceed, send the final adverse action notice.

State and local rules add limits. Many jurisdictions have ban-the-box or fair-chance laws that delay criminal history questions, and several states limit reporting of older records, often at seven years. The EEOC also advises that criminal history decisions be job-related and consistent with business necessity.

Employer checklist for CNA drug testing

• Publish a written drug-free workplace policy and get signed acknowledgments.
• Test after a conditional offer, and apply the same panel to all candidates in the role.
• Choose the panel and cutoffs before testing.
• Use a certified lab and an MRO for verification.
• Check state laws on marijuana, prescription use and testing notice.
• Run the FCRA disclosure and authorization before ordering background checks.
• Follow pre-adverse and adverse action steps, and keep records.
• Handle accommodation requests under the ADA with counsel.

Frequently asked questions

Do CNAs have to take a drug test?

No federal law requires it. Most testing comes from employer policy or state rules, and many healthcare employers test before hire.

What drugs does a CNA pre-employment test screen for?

Usually a urine 5-panel: marijuana, cocaine, opiates, PCP and amphetamines. Some employers choose a 10-panel that adds other prescription and drug classes.

Can an employer reject a CNA for a positive drug test?

Often yes, if the written policy and state law allow it. Use MRO-verified results, consider legitimate prescriptions, and consult counsel before any adverse decision.

Does a CNA background check follow the same rules as a drug test?

Background checks follow FCRA disclosure, authorization and adverse action steps. Drug testing is governed by your policy and state testing laws, so confirm both with counsel.
