Kratom is not included in the standard federal workplace drug-testing panels, which don't list mitragynine or any other kratom compound. Kratom-specific tests do exist, though, and employers, clinics, courts and some programs can order them, so whether "kratom shows up" depends entirely on what the test was ordered to look for.
This page is strictly informational. It explains what published sources say about testing panels, specialized tests and organizational rules as of September 28, 2026. It does not give advice on avoiding detection or passing a test, and it doesn't discuss detection times. If you're facing a test, the right move is to be honest with the employer, medical review officer or doctor involved.
21+ only. Kratom isn't FDA-approved for any use and is banned in some states and cities; see our state guide. This isn't medical or legal advice.
What standard drug-test panels include
The best-documented "standard" panel is the federal one set by HHS for federal workplace testing. The authorized testing panels, reissued in the Federal Register on March 13, 2026, list these urine analytes:
- Marijuana metabolite
- Cocaine metabolite
- Opioids: codeine, morphine, hydrocodone, hydromorphone, oxycodone, oxymorphone, 6-acetylmorphine, fentanyl, norfentanyl
- Phencyclidine (PCP)
- Amphetamine, methamphetamine, MDMA, MDA
Mitragynine, 7-hydroxymitragynine and kratom aren't mentioned anywhere in the document. Private employers' "5-panel" and "10-panel" tests are usually built around similar drug classes, but there's no single legal definition of a 10-panel, and labs offer add-ons. The only reliable way to know what a specific test covers is to ask whoever ordered it.
Kratom-specific tests exist
- Immunoassay screens. A commercial "CEDIA Mitragynine Immunoassay" is in clinical use, as described in a 2025 Clinical Chemistry abstract that evaluated it.
- Laboratory confirmation. That same abstract confirmed results with LC-MS/MS (liquid chromatography with tandem mass spectrometry), a lab method that identifies specific compounds.
- Research methods. Researchers continue to develop new mitragynine assays, for example an ELISA method for human urine published in ACS Omega in 2023.
So a test that includes a kratom panel can detect kratom compounds; a test that doesn't include one isn't looking for them.
What research says about false positives
We found two published findings, both conference abstracts published in journal supplements (short meeting summaries, not full peer-reviewed papers):
- Kratom and a methadone test. A 2020 abstract in the American Journal of Clinical Pathology reported that "a Kratom metabolite can cause false positive results in the Thermo Scientific CEDIA Methadone Metabolite (EDDP) immunoassay."
- Methadone and a kratom test. The 2025 Clinical Chemistry abstract reported that "high concentrations methadone and its metabolite EDDP may interfere and cause false positive results for mitragynine screening using the CEDIA Mitragynine immunoassay." Of 49 specimens that screened positive but were negative on LC-MS/MS, 82.6% contained methadone and EDDP.
Immunoassay screens can cross-react; that's why labs use confirmatory testing. If you take prescribed or over-the-counter medications or use kratom, tell the medical review officer or clinician so they can interpret results correctly. We found no official source saying kratom causes false positives on the standard federal opioid panel, and we don't speculate beyond the findings above.
Workplace, military and sports rules
Employers
Private employers set their own policies. A negative result on a panel that doesn't test for kratom doesn't mean kratom is allowed under a workplace policy; a written policy can cover substances beyond those a test looks for. Read your employer's written policy or ask HR.
Military
The US Navy prohibited kratom, mitragynine and 7-hydroxymitragynine in January 2026, with violations handled under the Uniform Code of Military Justice, Article 92, as reported by Yahoo News on January 14, 2026. Service members should check their branch's current orders.
Sports (WADA and USADA)
The U.S. Anti-Doping Agency says: "No, Kratom is not prohibited. For several years it was on the WADA Monitoring program, but as of 2018, it will no longer be monitored by WADA." USADA adds that "athletes are advised to steer clear of Kratom for health reasons" (page last modified March 6, 2026). A 2016 paper in Drug Testing and Analysis describes mitragynine monitoring in sports testing from that earlier period. Leagues and college associations can have their own rules; check with your organization.
7-OH is a separate issue
Concentrated 7-OH is the target of a July 2026 DEA temporary Schedule I action (DEA) and several state bans. KratomRated doesn't list 7-OH products; see what is 7-OH and why we don't list it.
Our recommendation: be honest
- With employers: if you're asked about substance use or are subject to a policy, answer truthfully and ask how kratom is treated.
- With doctors and pharmacists: tell them about kratom. The FDA warns consumers not to use kratom, citing risks including liver toxicity, seizures and substance use disorder, and your clinician can only account for it if they know.
- With a medical review officer: disclose kratom and any medications before or during review so results are interpreted correctly.
If you buy kratom
Know what's in the product. A batch certificate of analysis lists mitragynine and 7-OH content and contaminant results; see how to read a kratom lab report. Our kratom vendor list shows which vendors publish batch COAs, and best kratom vendors ranks them. For legal status where you live, see the state guide, and for background on the plant, kratom strains explained.
Risk note
The FDA has not approved kratom for any medical use. Kratom is banned in several states and some cities, and some employers and the military prohibit it regardless of state law. This page is general information, not medical or legal advice.
