This strip is made for the detection in human urine of benzodiazepines, which are part of anxiolytic drugs, hypnotics, anticonvulsants and muscle relaxants.


Benzodiazepines are generally prescribe to help some patients relax and relieve anxiety. However, these drugs are highly addictive, because of that, benzodiazepines require a real withdrawal supervised by a doctor to be stopped. Most patients are successful, but it still happens too often that others literally lose control of their consumption and sink into an addiction.

It also happens that some people subjected to high stress at work use benzodiazepines beyond a medical monitoring, which often leads to very strong dependence.


This test is a qualitative assay (type "NO / YES"), and thus delivers a "NEGATIVE" or "POSITIVE" result.
