Clear Test Cocain Surestep Drug Screen is a cocaine test based on an immunochromatographic in vitro test.
It is designed to quantitatively determine cocaine metabolites, benzoylecgonine, in human urine at a cut-off level of 300 ng/ml in 3 minutes.
The cocaine test is based on the principle of a specific immunochemical reaction between antibodies and antigens to analyze specific components in human urine samples.
- The quantitative analysis is based on the competition antibody binding between a drug compound and free drug, which be present in the urine sample being tested
- When a narcotic substance is present in the urine sample, it competes with the narcotic substance compound the limited amount of antibody-colorant compound
- When the amount of drug is equal to or greater than 300 ng/mg, it prevent the binding of free drug to antibodies
- Therefore, in a positive urine sample, no colored line appear in the test zone and there be a positive result, while the presence of a colored line indicates a negative result
- The test has a control line that serves as a procedural control
It should always appear in the control zone if the test is stored under good conditions and performed correctly.
Cocaine is initially excreted in the urine as benzoylecgonine for a short period.
Recommended for: General use
Key benefits: Manageability

Clear Cocaine Test Cassette. Sample collection and preparation: Approximately 150 ml of sample is required for each test. Fresh urine samples do not require any special handling or processing. The sample should be collected in a clean, dry, plastic or glass container. If the quantitative test is not performed immediately, the urine sample can be refrigerated at 2-8 °C and stored for up to 7 days or frozen. Samples should reach room temperature before testing. Urine samples that show significant sediment or cloudiness should be centrifuged or allowed to settle so that a clear liquid is obtained for testing. Quality control: The control strip is an internal reagent and procedure control. It will appear if the test is performed correctly and the reagents are reactivated. Control standards can be used to validate reagent performance and establish test reliability. Controls not provided with this test can be purchased. Test strip procedure: 1. Allow all materials and samples to reach room temperature. 2. Remove the test strip from the sealed foil. 3. Dip the strip into the urine sample so that the arrows point towards it. The sample level should not be higher than the maximum indicated by the arrow. 4. Hold the strip in the urine until a pink color appears in the test zone (approximately 20 seconds). 5. Remove the strip and place it on a clean, non-absorbent surface, face up, or leave it in the urine if the sample level is not higher than the maximum indicated by the arrow. 6. Read the result between 3-8 minutes. Do not interpret the result after 10 minutes! Interpreting the results: Negative: Two colored bands appear. The appearance of two colored bands, one in the test zone and one in the control zone, indicates a negative result. A negative result does not indicate the absence of amphetamines in the specimen. It only indicates that the level of amphetamines in the specimen is below the cut-off level. Positive: One colored band appears in the control line zone. No colored band is detected in the test line zone. This indicates that the level of amphetamines in the urine specimen is above the acceptable limit. Invalid: If there is no colored band in the control line zone, the test result is invalid. Retest the sample with a new test device. Note: A very faint colored band in the test line area indicates that the amount of amphetamines in the sample is close to the acceptable limit. These specimens and other positive samples should be confirmed using an alternative method such as GC/MS.

For in vitro and forensic use only. Do not use the product after the expiration date. Handle specimens with care, as they may be infectious. Do not open the sealed foil until you are ready to perform the test. Use a new container for each urine sample to avoid contamination of one sample by another; The test kit must be stored at a temperature between 2 and 86°F (30°C) and is effective until the expiration date;
