Identification methods

Any drugs and their metabolites are excreted in urine. Testing for addictive substances is based on the analysis of a urine specimen for their presence. We offer immunological identification methods. False-positive and false-negative results occur in rare cases. As a result, these identification methods can not be considered conclusive. For this purpose, a urine specimen needs to be analysed using a chromatographic method. Testing for addictive substances does not detect opiates, while heroine, morphine and codeine are recorded without a difference.

Duration of the possible identification of various substance groups in urine

The detectability of drugs in urine depends on the consumed quantity of the substance as well as the quantity of fluids the person drank. In addition, the excretion of the substances varies greatly among individuals. The dilation of the urine as a result of the addition of water or because of the consumption of large quantities of fluids is determined based on the Creatinine levels.
