Urine based screened tests for drugs of abuse of abuse range from simple immunoassay tests to complex analytical procedures. The speed of immunoassays has made them the most widely accepted method for screening urine for drugs of abuse.
The Drug Screen Card is based on the principle of highly specific immunochemical reactions of antibodies which are used for the analysis of specific compounds in biological fluids. The drug screen card is rapid, visual, competitive panel immunoassays that can be used for the simultaneous, qualitative detection of multiple drug metabolites in human urine.
