Q&A:

Why is there a temperature strip?

The primary purpose of the temperature strip is to verify the authenticity of the urine sample. By checking the temperature strip on the test cup, it can confirm whether the sample temperature falls within the normal human body temperature range, ensuring the sample is fresh and valid. This helps prevent sample tampering or forgery, improving the accuracy and reliability of the test results.

   - 32°C (90°F) to 38°C (100°F) is the normal temperature range for freshly excreted human urine samples.

   - If the urine temperature is below or above this range, it may indicate that the sample has been tampered with, forged, or is not freshly collected.

Why are there adulteration test strips? (Can be customized separately)

If the urine cup contains adulterated strips, please refer to the accompanying adulterated strips' standard colorimetric chart for result interpretation. If the color development of the adulterated strips meets the requirements of the color card, follow the operation steps to interpret the results of the test items. If the color of the adulterated bar does not meet the requirements of the color card, considering the possibility of adulteration of urine, whether it is necessary to re-sample and test again, it needs to be analyzed and judged according to the actual situation on the spot.

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.
