Drug test dipcard
The One Step Drug of Abuse Test is an immunoassay based on the principle of competitive binding. Drug which may be present in the urine specimen compete against their respective drug conjugate for binding sites on their specific antibody.
During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody. The antibody will then react with the drug-protein conjugate and a visible colored line will show up in the test line region of the specific drug strip. The presence of drug above the cut-off concentration will saturate all the binding sites of the antibody. Therefore, the colored line will not form in the test line region.
A drug-positive urine specimen will not generate a colored line in the specific test line region of the strip because of drug competition, while a drug-negative urine specimen will generate a line in the test line region because of the absence of drug competition.
To serve as a procedural control, a colored line will always appear at the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
HOW TO PERFORM THE TEST?
The test must be in room temperature (15ºC to 30ºC)
1. Open the sealed pouch by tearing along the notch. Remove the test dipcard from the pouch.
2. Immerse the dipcard into the urine with the arrow pointing towards the urine. Take the dipcard out after 10 seconds.
IMPORTANT: Do not allow the urine level to exceed the MAX (marker line), otherwise the test will not perform correctly.
3. Lay the test dipcard on a clean, dry, non-absorbent surface.
4. Read the results at 5 minutes. The drug test results remain stable for up to thirty minutes.
