Drug testing methods

Drug testing
The urine of screening of drugs
Kits of test drugs in the urine are available that on trials on site, or analysis in laboratory. Urine test is the most common trial type and used by programmes demanded by the trial federal of medicaments, but probably the least efficient.
The main disadvantages of the urine based on kits of screening of drugs is / (1) are. The easiness in which they can be "deceived" through falsification or simple substitution, unless the sample of samples is directly noticed, (2). Inability to discern currents / on-the-drogue of jobs, (3). the necessity of a bathroom, and (4). regarding SAMHSA-5 OR NIDA-5, impossibility of testing medicaments fluently victims of violence or badly used in the current society.
The saliva of screening of drugs
The saliva of etuis of medicaments (oral way) for tests friendly donors, invasive not and easy are very to gather the sample. He not ya no necessity of a bathroom to manage tests. The saliva of screening of drugs has tendency to discern the consumption of drug of last years. Also in these tests of screening are more difficult to falsify than the tests of drugs in the urine given that the sample can be got under direct supervision. According to trial, up to 8 different drugs were possible be disclosed. This method is the best method to determine the recent use and a potential indicator of depreciation is.
A disadvantage of the saliva of screening of drugs, it is that it is not approved by SAMHSA for an use with DOWRY / federal loaded the screening of drugs. Oral fluid is not considered to be a bio-hazard if he ya some visible blood, however, he must be manipulated with caution.
Spray (sweat) of screening of drugs
Spray (sweat) etuis of screening of drug are not - invasives. It is very easy to gather the sample and without bathroom is necessary to take the specimen. The window of detection is generally long and can discern the usage of drugs to a couple of the hours. These tests of drugs are relatively inviolable proof since they are difficult to manipulate. A laboratory is not necessary for the analysis.
The main disadvantage of spray or the sweat of screening of drugs is the fact that they are opened to pollution. Also big variations of the rates of production of possible sweat of the backers, to take into account conclusive results. There is not a lot of variety in these tests of drugs, because they are not as popular as the urine or the etuis of screening of drugs salivates. Their prices have tendency to be raised more by performed test. A major disadvantage of this method of test is the limited number of medicaments which can be discerned, and the capacity to produce immediate results.
How to pass a hair drug test
Hair of screening of drugs is possible give a much longer window of detection, which is very useful for the security of critical posts where he ya a zero tolerance of the usage of drugs. [15] Even if the tested person has the shaven head (perhaps in the course of preparation for trial), hair can also be taken from almost any other zone of the body. It includes the hair of the face, the armpits, the arms and the legs.
It costs more that urine tests, and it is necessary to have a laboratory on results. Trial on hair is more and more reliable that technology advances, and it not ya any means known to falsify a sample of hair to falsify the results of trial, in spite of what some retailers of advertising.
