Velo™ DOA Rapid Test (Strip)

The Velo^TM Multi-Drugs Rapid Test (Strip) is intended for the qualitative detection of multiple drugs of abuse, their metabolites, and alcohol in human urine. It is designed for professional use in clinical, forensic, and rehabilitation settings as a rapid screening tool to identify recent drug or alcohol consumption.

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.
