Kratom Urine Dip Test
One Step Kratom (KRA) Test Dip Card Package Insert
Package insert for testing of Kratom in Human Urine
A rapid, one step screening test for the simultaneous, qualitative detection of the specified drug and its metabolites in human urine.
For forensic use only.
INTENDED USE & SUMMARY
Urine based tests for drugs of abuse range from simple immunoassay tests to complex analytical procedures. The speed and sensitivity of immunoassays have made them the most widely accepted method to screen urine for drugs of abuse.
The One Step Kratom（KRA）Test Dip Card is a lateral flow chromatographic immunoassay for the qualitative detection for the specified compound and its drug metabolites in urine at the following cut- off concentrations:
This test will detect other related compounds, please refer to the Analytical Specificity table in this package insert.
This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
Kratom leaves produce narcotic-like effects when smoked, chewed, or drank as a suspension, which have recently attracted significant attention due to increased use in Western cultures as an alternative medicine. It is used in therapy for opiate addiction and chronic pain management. The addiction potential and adverse health consequences are becoming an important issue for health authorities. Extensive use of kratom results in prolonged sleep. The withdrawal symptoms include hostility, aggression, muscle pain and inability to work. The One Step Kratom (KRA) Test Dip Card yields a positive result when the Mitragynine in urine exceeds 600 ng/mL.
Each test in the Test Strip contains mouse monoclonal antibody-coupled particles and corresponding drug- protein conjugates. A goat antibody is employed in each control line.
- For forensic use only.
- Do not use after the expiration date.
- The device should remain in the sealed pouch until use.
- All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
- The used device should be discarded according to local regulations.
STORAGE AND STABILITY
Store as packaged in the sealed pouch either at room temperature or refrigerated (2-30°C). The Test Strip is stable through the expiration date printed on the sealed pouch. The Test Strip must remain in the sealed pouch until use. DO NOT FREEZE. Do not use beyond the expiration date.
SPECIMEN COLLECTION AND PREPARATION
The urine specimen must be collected in a clean and dry container. Urine collected at any time of the day may be used. Urine specimens exhibiting visible precipitates should be centrifuged, filtered, or allowed to settle to obtain a clear specimen for testing.
Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For prolonged storage, specimens may be frozen and stored below -20°C. Frozen specimens should be thawed and mixed well before testing.

Materials Required But Not Provided
- Specimen collection container
DIRECTIONS FOR USE
Allow the test device, and urine specimen to come to room temperature [15-30°C (59-86°F)] prior to testing.
- Remove the test device from the foil pouch.
- Remove the cap from the test device. Label the device with patient or control identifications.
- Immerse the absorbent tip into the urine sample for 10-15 seconds. Urine sample should not touch the plastic device.
- Replace the cap over the absorbent tip and lay the device flat on a non-absorptive clean surface.
- Read results at 5 minutes.
DO NOT INTERPRET RESULT AFTER 10 MINUTES.
INTERPRETATION OF RESULTS
(Please refer to the illustration above)
NEGATIVE:* Two lines appear. One red line should be in the control region (C), and another apparent red or pink line adjacent should be in the test region (Drug/T). This negative result indicates that the drug concentration is below the detectable level.
*NOTE: The shade of red in the test line region (Drug/T) will vary, but it should be considered negative whenever there is even a faint pink line.
POSITIVE: One red line appears in the control region (C). No line appears in the test region (Drug/T). This positive result indicates that the drug concentration is above the detectable level.
INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test using a new test panel. If the problem persists, discontinue using the lot immediately and contact your manufacturer.
A procedural control is included in the test. A colored line appearing in the control line region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.
Control standards are not supplied with this kit. However, it is recommended that positive and negative controls be tested as good laboratory practice to confirm the test procedure and to verify proper test performance.
- The One Step Kratom（KRA）Test Dip Card provides only a qualitative, preliminary analytical result. A secondary analytical method must be used to obtain a confirmed result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method.
- There is a possibility that technical or procedural errors, as well as other interfering substances in the urine specimen, may cause erroneous results.
- Adulterants, such as bleach and/or alum, in urine specimens may produce erroneous results regardless of the analytical method used. If adulteration is suspected, the test should be repeated with another urine specimen.
- A positive result does not indicate level or intoxication, administration route or concentration in urine.
- A negative result may not necessarily indicate drug-free urine. Negative results can be obtained when drug is present but below the cut-off level of the test.
- The test does not distinguish between drugs of abuse and certain medications.
- A positive result might be obtained from certain foods or food supplements.
The following table lists the concentration of compounds (ng/mL) that were detected positive in urine by the One Step Kratom (KRA) Test Dip Card at a read time of 5 minutes.
A study was conducted to determine the cross-reactivity of the test with compounds in either drug-free urine or Mitragynine positive urine. The following compounds show no cross-reactivity when tested with the One Step Kratom (KRA) Test Dip Card at a concentration of 100 g/mL.
