Imagine You have just come across this miraculous herb, Kratom, and have started to be fascinated by this herbal supplement for its fantastic health benefits. But before you fully get the most out of it, there’s a crucial detail to consider – Urine tests. From job screenings to routine check-ins, those little cups pop up everywhere. Here’s the question: How does Kratom play into all of this? How Kratom and urine tests are related, and why would some companies conduct urine tests for Kratom? Let’s get everything crystal clear in this eye-opening blog.  

Understanding Kratom

Kratom is a Southeast Asian herb that grows on a vast tropical evergreen tree botanically as Mitragyna Speciosa. It has a rich history in traditional medicine and cultural practices. Folks consume it in various forms like dried leaves, powders, capsules, and extracts and get a discomfort-free state, enhanced mood, energy, motivation, and focus.

Does Kratom Show Up On A Drug Test?

Yes, Kratom can show up on specific drug tests. While standard drug tests like those for employment purposes typically do not screen for Kratom, specifically, specialized tests such as the 10-panel drug screen may detect its metabolites in urine. But worry not usually; Kratom is not typically included in standard drug screenings and is not considered an illegal substance in many regions. 

How Long Does Kratom Stay In Your System?

The duration Kratom powder stays in your system can vary based on several factors. Your physiology, the dose you take, frequency of use, and metabolic rate hugely affect the complete elimination of the herb from your system. Typically, Kratom’s effects last around 5 to 7 hours, but its metabolites can be detectable in urine for up to several days after use. Kratom can be noticeable for approximately 1 to 2 days for those who use Kratom infrequently, while for regular users, it can be detected for up to 5 to 7 days or longer. 

The Legality Of Kratom And Why Urine Tests Are Conducted?

The legality and regulation of Kratom are essential considerations for folks, especially those living in areas where the use of the herb is restricted. While Kratom is federally legal in the United States, it’s banned in some regions, and companies usually conduct drug tests where it is not permitted to be used. These tests help maintain and uphold legal standards and drug-free workplaces.

How Do Urine Tests Work?

Urine tests, or you can also say urinalysis, function by detecting the presence of specific substances or their metabolites in urine samples. These tests use immunoassays, gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS) to analyze urine samples. Immunoassay tests are commonly used for initial screenings, while GC-MS and LC-MS provide confirmatory results with higher accuracy and sensitivity. The detection windows of these tests vary depending on the substance being analyzed and can range from a few hours to several days. 

Kratom’s Interaction With Urine Tests

Kratom’s interaction with urine tests is influenced by its chemical composition and metabolic pathways. Kratom contains 40+ unique alkaloids, but mostly mitragynine and 7-hydroxy mitragynine are responsible for their health-promoting effects. These alkaloids undergo hepatic metabolism upon ingestion, primarily through cytochrome P450 enzymes, resulting in various metabolites. These metabolites also include mitragynine pseudoindoxyl and mitragynine glucuronides, which are also detectable in the urine samples of the users.

Understanding these metabolic pathways helps in interpreting urine test results accurately. There exist some factors that may cause variability in the results depending upon the users, such as the type of strain being used, how potent the strain is, the metabolism of the user, and how often the user uses Kratom. High potency strains and frequent users usually come up with longer detection windows as compared to the folks with lower metabolism and less frequent use of Kratom or those who take mellow strains with lesser rich alkaloid profile. 

What Are The Limitations Of Detecting Kratom In Urine Tests?

Do you know it is not a straightforward process to detect Kratom in the urine test? Let’s have a look at the limitations that may cause wrong interpretations. 


Sometimes, Immunoassay tests used for detecting Kratom in urine may cause false positives due to cross-reactivity. The situation occurs when tests for Kratom in urine might say it’s there when it’s not. It usually happens because the test gets confused and reacts to other things in your body instead of just Kratom. The result might be wrong because of this mix-up.

For example, a test designed to detect opioids may produce a positive result in the presence of Kratom metabolites due to their structural similarity, even though Kratom itself isn’t an opioid. Cross-reactivity complicates result interpretation, and additional confirmatory tests are required to distinguish Kratom from other substances accurately. It is especially important in areas where kratom use is not legal, and false positives can have employment-related consequences.

Metabolite Variability

When Kratom is metabolized, it generates different types of metabolites having different chemical compositions and concentrations. The variability poses challenges for urine tests since individuals may produce other metabolites in varying amounts, making it challenging to establish standardized detection methods. 

Additionally, factors such as age, genetics, and co-existing medical conditions can further influence metabolic pathways and may cause variations in metabolite composition among individuals. For this reason, standardized cutoff levels for positivity become challenging, interpretation of the tests is complicated, and accuracy is affected often.

Threshold Levels

Since determining reliable cutoff levels for Kratom metabolites in urine tests is challenging due to individual factors, this variability makes it challenging to establish consistent thresholds for positivity that accurately reflect Kratom use. Moreover, different rules in different places and no set way to test can make it hard to decide how much Kratom is too much and complicate the reliability of the test results. 

Short Detection Window

Kratom’s short elimination half-life, which is up to 7 days post-consumption, results in a narrow timeframe for detection in urine. The short window is a massive challenge for wrong interpretation if timely testing is not done. For example, in cases where recent Kratom use needs to be confirmed, delayed testing beyond this window may result in false-negative results because Kratom metabolites become undetectable in urine. 

Matrix Effects

Urine’s complex composition can interfere with analytical techniques used for detecting Kratom metabolites and lead to inaccurate results. The situation is known as Matrix effects. The interference may lead to false positives or negatives and may cause wrong interpretations, impacting decisions in employment-related contexts.

What Does The Research Say About Kratom And Urine Tests?

Let’s have a look at a recent study by Helander and Rylski that is about the challenges in detecting Kratom compounds in urine tests. The research revealed that standard methods struggle to distinguish mitragynine from its diastereomers due to their similar structures. Despite efforts to improve differentiation, all urine samples positive for mitragynine also showed the presence of other diastereomers. The research directly highlights the ongoing difficulties in accurately assessing Kratom use through conventional urine tests.

What Are The Strategies For Minimizing False Positives Related To Kratom Use In Urine Tests?

Confirmation Testing

Confirmation testing methods like gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS) can be utilized to confirm the presence of Kratom metabolites. These methods offer higher specificity and can distinguish Kratom from other substances.

Selective Testing Panels

Selective testing panels can be implemented that specifically target Kratom metabolites rather than relying on broad-spectrum immunoassay tests. By focusing on the unique markers of Kratom use, particular testing panels can minimize cross-reactivity with unrelated substances.

Establishing Validated Cutoff Levels

Establishing validated cutoff levels for Kratom metabolites based on comprehensive research and analysis can also eliminate the risks of false positives. By determining accurate positive thresholds, laboratories can minimize false positives and enhance result accuracy.

Educating Laboratory Staff

Comprehensive training and education to laboratory staff on the intricacies of Kratom metabolism and detection should be provided. By equipping staff with in-depth knowledge of Kratom’s chemical composition and potential cross-reactivities, laboratories can enhance result interpretation accuracy.

Sample Dilution And Dilute-And-Shoot Approaches

Sample dilution techniques or dilute-and-shoot approaches in urine testing can be employed to reduce the risk of false positives. These methods involve diluting urine samples with suitable solvents or buffers to minimize interference from urine matrix components and thereby improve the accuracy and reliability of test results.
