The following is a summary of the single drug testing kits description.
These tests are mainly usually applied to screen samples for presence of some illegal substance or its metabolites. There are different tests for different drugs.
In the event that drugs or their metabolites are detected, then the sample is normally tested again using an even more sensitive test such as Gas Chromatography and Mass Spectrometry.
We have two different formats: dip strips or cassettes. For protection from the possible mistakes cassettes much better, even they are cost a little bit more. The chemical regents absolutely the same, and difference is only in technique of delivery. Dip strips as it understandable from the name, must to be get deep in to the urine specimen and it is a way to do a mistake if you under or over deep the strip. Cassettes are more convenient device because it is includes small dropper and you put several drops of the urine in to the specimen’s window. You can count the quantities exactly according to test instruction.
