SoFarma The marijuana test Description Rapid lateral flow immunochromatographic assay for the determination of 11-nor-delta9-THC-9 COOH (THC metabolite) in human urine at a cut-off concentration of 50 ng/mL. This test provides only preliminary analytical data. More specific chemical methods should be used to confirm the analytical result. Gas chromatography/mass spectrometry (GC/MS) is considered the preferred confirmatory method. Any result for determining the presence of drugs of abuse must be linked to clinical considerations and professional judgment, especially when the preliminary result is positive. How to use Collect the urine sample in a clean, dry container. Urine samples collected at any time of the day can be used. Urine specimens can be stored at 2-8°C for up to 48 hours. For longer storage, specimens can be frozen and stored below -20°C. Frozen specimens should be thawed and mixed thoroughly before use. Before performing the test, bring the test device and urine sample to room temperature (15-30°C). Remove the test device and use it as soon as possible. Place the device on a clean, flat surface. Hold the pipette vertically and dispense three drops of urine (approximately 120 mcL) into the sample well (S) of the test device. Avoid the formation of bubbles. Start the timer and read the result after 5 minutes. Do not interpret the result after 10 minutes. Interpretation of results NEGATIVE: Two colored lines appear, the test line (T) and the control line (C). The color intensity of the test line (T) may vary, but this has no influence on the interpretation of the test results; the result should still be considered negative. A negative result indicates that the concentration of marijuana is below the detectable level (50 ng/mL). POSITIVE: Only the control line (C) appears. The test line (T) does not appear. A positive result indicates that the concentration of marijuana is above the detectable level of 50 ng/mL. INVALID: No lines appear or only the test line (T) appears. The result is considered invalid. It is recommended to repeat the test. If the problem persists, contact your supplier. warnings The product is not intended for medical or diagnostic use. Keep the device in the closed packaging until ready to use. All samples should be considered potentially hazardous and therefore should be handled with the precautions necessary for use with potentially infectious products. After use, the test should be disposed of according to local regulations. The test provides a qualitative result that should be considered preliminary. A second analytical method should be considered to confirm the result. Gas chromatography/mass spectrometry (GC/MS) is considered the preferred confirmatory method. It is possible that technical or procedural errors, as well as interfering substances present in the urine sample, can lead to erroneous results. A positive result indicates the presence of the drug or its metabolites, but not the level of intoxication, route of administration, or concentration in urine. A negative result does not necessarily mean that the urine sample does not contain drugs. A negative result can occur when the drug is present, but at a concentration below the tests detection level. The test cannot distinguish between the drug and a drug containing the same substance. Conservation Store at a temperature between 2°C and 30°C. Do not freeze. Shelf life in intact packaging: 24 months. Format The kit contains: - testing device; - pipette; - the prospectus. Code SF010
