Drug Test Marijuana
Description
A lateral flow chromatographic immunoassay for the detection of 11-nor-delta 9 -THC-9 COOH (THC metabolite) in human urine at a cutoff concentration of 50 ng/mL.
The test is based on the principle of competitive binding. Drugs that may be present in the urine specimen compete with their drug conjugate for the same antibody binding sites. During testing, a urine sample migrates upward by capillary action. Marijuana, if present in the urine sample below 50 ng/mL, will not saturate the binding sites of the antibody-coated particles in the test strip. Antibody-bound particles will be captured by the immobilized conjugate and a visible colored band will appear in the test region. The colored band will not appear in the relevant area if the drug level in the urine sample is higher than its cut-off, as all relevant antibody binding sites will be saturated.
A drug test positive urine specimen will not cause the color band to form due to drug competition, while a drug test negative urine specimen or a sample containing a cut-off concentration of the drug will cause the color band to form in the specific test area.
As a control of the procedure, a colored band will appear in the relevant area, indicating that a correct amount of sample has been used and that migration on the membrane has taken place.
This test provides only a preliminary analytical test result. A more specific alternative chemical method must be used to obtain a confirmed analytical result. Gas chromatography-mass spectrometry (GC/MS) is the preferred confirmatory method. Any result for determining the presence of drugs of abuse should be based on clinical considerations and professional judgment, particularly when the preliminary result is positive.
How to use
Sample collection and preparation
The urine sample must be collected in the appropriate jar, present inside the package, clean and dry. Urine can be collected at any time of the day. Urine specimens with visible precipitates should be centrifuged, filtered, or settled to obtain a clear specimen for testing.
Urine samples may be stored at 2-8°C for up to 48 hours prior to testing. For long-term storage, samples may be frozen below -20°C. Frozen samples must be thawed and mixed before testing.
Testing procedure
Allow the panel and urine sample to reach room temperature (15-30°C) before testing.
Remove the test device from the sealed pouch and use it as soon as possible.
Place the test device on a flat, clean surface. Hold the dropper vertically and transfer 3 full drops of urine (approximately 120 mcL) into the sample well (S) of the test device, then start the timer. Avoid trapping air bubbles inside the well.
Wait for the red lines to appear. The result should be read after 5 minutes. Do not interpret the result after 10 minutes.
Interpretation of results
POSITIVE: A colored line in the Control Line Region (C) but no line in the Test Region (T) for the specific drug indicates a positive result. This indicates that the drug concentration in the sample exceeds the cut-off designated for the specific drug.
