ASSAY PROCEDURE Back to Products page
If specimen, control, or test devices have been stored at refrigerated temperatures, allow them to warm to room temperature before testing.
Do not open test device pouch until ready to perform the test.
1. Remove the test device from the sealed pouch, and remove the cap to expose the sampling tips.
2. Immerse the sampling tips into the urine specimen for about 15 seconds. Do not immerse above where the sampling tips go into the plastic body. Place the test device on a flat surface with the cap on.
3. Wait 5 minutes to read Positive results. Do not interpret result after 10 minutes.
INTERPRETATION OF RESULTS
Negative (-): Two colored lines should be observed in the viewing window. The line in the test region is the drug probe line. The line in the control region is the control line, which is used to indicate proper performance of the device. The test line may have varying intensity either weaker or stronger in color than that of the control line.
Positive (+): Only one colored line appears in the control region. The complete absence of a test line with a clear white background indicates a positive result.
Invalid: No colored line appears in the control region. If the control line does not form, the test result is inconclusive and should be repeated.
