Drug testing

General information

In general drug testing information, trials of medicaments are divided into two groups. The first group is sophisticated laboratory tests of drug. In this type of test the donor gives a sample of urine, of blood, of hair or of saliva / saliva or hair for an employer, doctor, civil servant made responsible for applying law, or a centre of devoted test. After the sample of the donor, the sample with an inviolable Seal / stamp of integrity is sent for analysis in laboratory. The main advantages of this type of test are precision, the legal solidity and capacity to customise tests for a particular demographic group. Disadvantages are generally costs linked to necessity for the sites of collection (urine, blood), and delay in the reception of results (until 5 days). The other type, on the screens of the site, made with a not very expensive kit, allow results in some minutes. Besides the urine, samples of urine of replacement, as saliva or buccales secretions were used in trials on place to eliminate problem "to beat tests" (in another way known as the falsification of sample or of substitution). Unfortunately, the common / oral saliva trial methods of fluids are not rather sensitive to discern drugs of many abuses. Another improvement of the screen of the site, is the Cut of the test of urine which gathers and discerns in the device the same container.

On the site Screen Test and of laboratories of analysis

On screens site give qualitative results fast, and when she is supplemented by tests in laboratory of confirmation, as GC / MS analyses, are possible be defended before a court of right. One - trial site of quick results in most States not to act as proof. However, result screen Quick determines if an analysis in laboratory is necessary. Habitually, of presumption of positive specimens is sent for analysis in laboratory and an usage of drugs seropositive determined by the result of analysis of laboratory.

Right personnels

Subject should have the right to ask for a sample of Split to be sent in a laboratory of its choice for a new analysis. It is demanded that the ré-analysis of samples have to be polluted by the reactive of initial screening test. In most DIP common, then to read the type of tests and the many tests of the Cut of urine, the sample is polluted by the reactive of test. To avoid a new sample, the sample of urine should be pre-slit before trials of these devices. CupLab Coupe of the test of urine, however, schisms sample of urine automatically when she is gathered.
