Does Kratom or 7-OH Show Up on a Drug Test?
Updated October 14, 2026
Kratom is a plant product whose main alkaloids are mitragynine and 7-hydroxymitragynine, the compound now sold on its own as 7-OH. Neither is on a standard 14-panel drug screen, and Testr does not claim otherwise.
On the laboratory's menu both appear under Opioids & opiate analogs, as 7-Hydroxymitragynine (kratom) and Mitragynine (kratom).
Is kratom on the 14-panel test?
No. The clinical cassette read at every Testr visit screens 14 panels: amphetamines, methamphetamine, THC, cocaine, opiates, oxycodone, methadone, benzodiazepines, buprenorphine, barbiturates, MDMA, PCP, fentanyl and EtG. There is no kratom panel on it, and Testr does not claim that kratom or 7-OH sets off the opiate panel or any other. A negative 14-panel read says nothing about kratom either way.
That is true of most rapid drug tests, which is why "7-OH drug test" is such a common search: the products are sold openly, and the standard screen was never designed to look for them.
How kratom and 7-OH are detected: laboratory confirmation
The CAP-accredited laboratory Testr uses confirms an 81-substance menu, and both kratom alkaloids are on it. Mitragynine is the leaf's most abundant alkaloid; 7-hydroxymitragynine is the one behind the products sold as 7-OH. Because the laboratory lists them separately, its report shows a measured level for each rather than a single line for "kratom".
This only happens when laboratory confirmation is part of the order. Choose the Rapid Test with Laboratory Confirmation when you book, or, if the At-Home Rapid Test has already been collected, upgrade from the app within 2 hours of collection, while the specimen is still viable. The laboratory reports in about 72 hours. Every laboratory report goes to a Medical Review Officer (MRO), a physician who reviews laboratory-confirmed results and accounts for valid prescriptions before the report is released.
What about a detection window?
This page does not quote one. Testr publishes detection windows only for the 14 screened panels, where they sit alongside a cutoff the on-site cassette actually uses, and it will not hand you a number for kratom that it has not verified. What the laboratory reports is the measured level found in the specimen on the date of collection. That number, and that date, are what a reviewing professional works from.
How Testr tests for it
A certified collector comes to your home or office anywhere in the Los Angeles area, seven days a week between 7 AM and 7 PM, with the earliest window 3 hours after you book. Identity is verified at the door with a PIN, specimen temperature is checked at collection, the 14-panel cassette is read on the spot, and the sealed specimen travels to the laboratory under a chain-of-custody code. Results are released only to the ordering account. With the account holder's written consent, the laboratory report can also be released directly to a named third party. Booking for a family member or a client works the same way: choose "Someone else" and their name goes on the record.

Does 7-OH show up on a drug test?
Not on a rapid cup, for the same reason kratom does not: there is no strip for it. On the laboratory side the answer is yes. 7-hydroxymitragynine has its own line on the 81-substance confirmation menu, at a 10 ng/mL cutoff, so a laboratory report shows a measured level for 7-OH itself, whether it came from kratom leaf or from a product sold as 7-OH on its own. A practice ordering for a client, or a parent ordering for a teenager, gets that answer by choosing the Rapid Test with Laboratory Confirmation: see Testr for professionals and Testr for parents.
Questions about kratom and 7-OH
Does kratom show up on a drug test?
Not on a standard 14-panel rapid screen. Testr's on-site cassette has no kratom panel, and Testr does not claim that kratom or 7-OH triggers any of the 14 panels. The laboratory's confirmation menu does list both kratom alkaloids, mitragynine and 7-hydroxymitragynine, so they are detected only when laboratory confirmation is ordered.
What is 7-OH?
7-OH is short for 7-hydroxymitragynine, one of the alkaloids in the kratom leaf, now also sold on its own as a separate product. The laboratory lists it as its own analyte, at a 10 ng/mL cutoff, separate from mitragynine at 2 ng/mL.
Which Testr test do I need for kratom or 7-OH?
The Rapid Test with Laboratory Confirmation. The rapid 14-panel read still happens on site, then the sealed specimen goes to a CAP-accredited laboratory for LC-MS/MS analysis against its full 81-substance menu, with results in about 72 hours. Every laboratory report is reviewed by a Medical Review Officer (MRO), a physician who reviews laboratory-confirmed results and accounts for valid prescriptions before the report is released.
Does a negative rapid test mean no kratom?
No. A negative 14-panel read says nothing about kratom either way, because the cassette does not look for it. Only the laboratory report answers the question.
Does 7-OH show up on a drug test?
Not on a rapid cup. 7-hydroxymitragynine is on the laboratory's 81-substance confirmation menu at a 10 ng/mL cutoff, so it is reported, as its own measured level, when laboratory confirmation is ordered.
Does kratom cause a false positive for opiates?
Mitragynine and 7-hydroxymitragynine are structurally unlike morphine, and Testr does not claim its MOR panel reacts to them. Rare cross-reactions on some cups have been reported, which is one more reason a screen is never the last word: laboratory confirmation measures each compound by LC-MS/MS and reports the kratom alkaloids as themselves, not as an opiate.
