Does Kratom Show Up on a Drug Test? Detection Times & What to Know

schedule6 min readcalendar_todayUpdated Nov 29, 2025

GUIDE

Standard 5-panel and 12-panel drug tests do NOT detect kratom. However, specialized tests for mitragynine exist and are increasingly used by certain institutions.

articleStandard Drug Panels

Panel Type	Substances Tested	Detects Kratom?
5-Panel	THC, Cocaine, Opiates, PCP, Amphetamines	No
10-Panel	5-panel + Benzos, Barbiturates, Methadone, Propoxyphene, Quaaludes	No
12-Panel	10-panel + MDMA, Oxycodone	No

Important: Kratom does NOT cause false positives for opiates. The standard opiate panel tests for morphine metabolites, which kratom does not produce.

articleSpecialized Kratom Tests

Specific tests for mitragynine do exist:

Who uses them: Probation/parole offices, pain management clinics, drug courts, some treatment centers, military (in some cases)
Cost: Additional $50-150 on top of standard panel
Detection: Tests for mitragynine and sometimes 7-OH

If you're concerned, ask specifically whether kratom is included in your test panel.

articleDetection Windows by Sample Type

Sample	Detection Window	Notes
Urine	5-7 days	Most common, longer for heavy users
Blood	24-48 hours	Short window, rarely used
Hair	Up to 90 days	Expensive, uncommon
Saliva	Unknown	Not well-studied for kratom

Factors affecting detection: Dose, frequency, metabolism, body fat, hydration, liver function.

articleEmployment & Legal Considerations

Most employers do not test for kratom. Standard pre-employment screens use 5-panel or 10-panel tests that don't include kratom.

However, certain industries may test:

Pain management clinics (monitor patient compliance)
Drug courts and probation
Some government contractors
Safety-sensitive positions (case by case)

In banned states, a positive kratom test could have legal consequences.

help_outlineFrequently Asked Questions

No. Kratom does not metabolize into morphine-like compounds. Standard opiate immunoassays do not cross-react with mitragynine.

Mitragynine has a half-life of approximately 24 hours. For most users, it's undetectable in urine within 5-7 days of last use.

Some do, some don't. It depends on jurisdiction and individual terms of probation. If kratom is illegal in your state or specifically prohibited by your probation terms, testing is more likely.
