The tests are competitive immunoassays for the qualitative determination of various drugs and drug metabolites in human urine.

The tests are in vitro diagnostic and intended for professional use only. Rapid tests give only visual, qualitative and preliminary results.

All rapid tests follow the same proven principle. The patient sample is placed on the sample area of the test and moved along the test strip by capillary forces. Along with the urine sample, gold-conjugated antibodies localised in the sample field region are transported along the test strip.
