FEATUERS:

Marijuana test kit: This is an instant test kit for marijuana, containing 5 test cards and 1 instruction manual. It is applicable to home testing, workplace testing, school/college/university substance testing, substance abuse rehabilitation centers, and criminal justice/law enforcement testing.
99% accuracy: Over 99% accurate in detecting Marijuana (THC) at a cut-off of 20ng/ml, more sensitive than the standard typical cut-off of 50ng/mL.
Rapid and simple to use: Dip the test into the urine sample for 10-15 seconds. Then, read the results for 5 minutes.
Clear and reliable: It is harmful if 2 lines appear and positive if only the control line appears in 5 minutes.
Worry-free: Every dip card is packaged in a sealed package to ensure cleanliness. Our service team is always here to solve your problem within 24 hours.

HOW TO USE:

1. Immerse the test strips vertically into the urine sample.
2. Remove the test card after 10 seconds. Lay the test flat on a clean, dry, non-absorbent surface, and then begin timing.
3. Wait for colored lines to appear. Interpret the test results at 5 minutes.

INTERPRET THE RESULTS:

Negative: Two lines appear (C and T).
Positive: One line appears at the control region (C).
Invalid: No line appears in the control region (C).

CUT-OFF LEVELS:

POTENTIAL ISSUES:

• No bands appear on the strip (Replace the test card and retest according to the instructions):

  The product has expired, and the C line does not appear.

  During sample application, the sample exceeds the MAX line, causing the gold-labeled antibodies to enter the sample well and disrupting the chromatographic flow. This prevents the antigen-antibody reaction from forming.

• Only the T line appears, and the C line is absent (Replace the test card and retest according to the instructions):

  The product is damp, rendering the absorbent end of the test strip ineffective, and the chromatographic flow cannot fully form.

• The drug user does not test positive (Collect a new sample the next day and retest):

  The drug was recently used, and the substance has not yet been metabolized into the sample.

  No recent drug use; collect alternative samples such as hair for testing.

• Cross-reaction with other drugs (Check the manual to see if cross-reaction is mentioned; if not, contact the manufacturer):

  Different products may cross-react with different drugs.

• The discrepancy between drug users and confirmation results:

  False Positive:

  The sample contains cross-reactive substances.

  Check the composition of drug metabolites. During confirmation analysis, ensure that protein-bound metabolites have been preprocessed.

  False Negative:

  Differences between the product and confirmation standards (commonly occur near the CUTOFF threshold).

  Conduct a quantitative analysis of the sample to determine the drug concentration range.

• T line appears, but the color is faint:

  The sample contains a small amount of the drug, and the concentration does not reach the CUTOFF value. This is generally interpreted as a negative result.
