Our factory produce drug of abuse test: 3.0 strip, cassette with competive price. Our drug tests are all CE certified.

The Drug screening MDMA test is an immunoassay based on the principle of competitive binding. The drug or the metabolites, which may be present in the urine specimen competes against limited antibody binding sites. During testing, a urine specimen migrates upward by capillary action. MDMA, if present in the urine specimen below 500ng/mL, will not saturate the antibody binding sites. The colored antibody-particles conjugate will then be captured by immobilized MDMA-protein on membrane and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the MDMA level is at or above 500ng/ml, because it will saturate all antibodies’s binding sites.

A drug-positive urine specimen will not generate a colored line in the test line region 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 if the test has been performed properly.
