Description
Rapid lateral flow immunochromatographic test for the determination of cocaine in human urine at a cut-off concentration of 300 ng/mL.
This test provides preliminary analytical data only. More specific chemical methods should be used to confirm the analytical result.

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 samples can be stored at 2-8 °C for up to 48 hours. For longer storage, samples can be frozen and stored at temperatures below -20 °C. Frozen samples should be thawed and mixed thoroughly before using.
Before testing, 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 test device on a clean, flat surface.
Hold the dropper vertically and dispense three drops of urine (approximately 120 mcL) into the specimen well (S) of the test device. Avoid the formation of air 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 relevance for the interpretation of the test results, the result must still be considered negative.
The negative result indicates that the concentration of benzoylecgonine is below the detectable level (300 ng/mL).

POSITIVE: Only the control line (C) appears. The test line (T) does not appear.
The positive result indicates that the concentration of benzoylecgonine is above the detectable level of 300 ng/mL.

INVALID: No line appears or only the test line (T) appears. The result is considered invalid. It is recommended to repeat the test. If the problem persists, contact the seller.

Warnings
Product not intended for medical or diagnostic use.
Keep the device in the closed package until ready to use.
All samples should be considered potentially hazardous and should therefore be handled with the precautions for use with potentially infectious products.
After use, the test must 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) are considered preferred confirmatory methods.
It is possible that technical or procedural errors, as well as interfering substances present in the urine sample, may cause 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 is drug-free. A negative result may occur when the drug is present but at a concentration below the detection level of the test.
The test cannot distinguish between the drug and a medicine containing the same substance.
