The Rapid Exams Multi-Drug Test is a lateral flow chromatographic immunoassay for the qualitative detection of multiple drugs and drug metabolites in urine.

The Rapid Exams Multi-Drug Test is an immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against their respective drug conjugate for binding sites on their specific antibody.
