A drug test is a scientific examination of the biological sample for example urine, hair, blood, breath, sweat or oral fluids or saliva. It is used to rule the presence or absence of parent drugs or metabolites. It is majorly used for the detection of steroids present in sportsmen, employers or parole or probation officers for drugs prohibited by the law. These tests are done on the spot instantly.
The 5 panel Drug Test Kit is a unit which contains 5 panels or strips. The seal has to be broken and dipped into urine up to the level indicated on the strip and the reading shows at the bottom indicating the presence of the specific drug. If the strip is dipped too much into the urine the kit becomes invalid.
