Velo™ DOA Rapid Test (Cassette)

The Velo^TM Multi-Drugs Rapid Test (Cassette) is intended for qualitative detection of multiple drugs, their metabolites, and alcohol in human urine. It is designed for use by healthcare professionals as a screening tool for drug abuse, providing rapid results for a broad range of substances in forensic, workplace, rehabilitation, and clinical settings.

During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody. The antibody will then react with the drug-protein conjugate and a visible colored line will show up in the test region of the specific drug dipstick. The presence of drug above the cut-off concentration will saturate all the binding sites of the antibody. Therefore, the colored line will not form in the test region.
A drug-positive urine specimen will not generate a colored line in the specific test region of the dipstick because of drug competition, while a drug-negative urine specimen will generate a line in the test region because of the absence of drug competition.
To serve as a procedural control, a colored line will always appear at the control region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
