It is really shocking that drug abuse cases have been increasing day by day. Different drug testing methods have been introduced to detect the presence of illegal drugs in one's sample. So, every adult citizen should have sufficient knowledge about the life threatening risks due to drug addiction and also a variety of drug tests.

In most of the drug testing methods, a person's blood is used as the sample for drug identification. But for more accuracy of result, it is recommended to use urine in place of blood. But the urine drug test is more expensive. One disadvantage of using urine for drug testing is it can not provide reliable information regarding the history of drug abuse. On the other hand, blood drug test can provide the lab technicians with the details of a person's drug history. Blood analysis can accurately prove if a person is under the influence of the banned drugs for a good period of time or not. But some experts are of the view that even the blood drug testing fails to produce an accurate result when it comes to exhuming the history of drug abuse of a typical individual.

In spite of being a lesser choice for drug testing, blood is used as a sample in many a lab. Apart from discovering the history of drug addiction, the blood drug test leaves no scope for the addicted to resort to any sort of trick. As privacy is not a requirement to collect the sample, so cheating is not possible in this case. On the other hand, though urine drug testing is a much superior choice, still the possibility of cheating can not be overruled. Truly speaking, the risk of cheating is very high.

Hair drug test is another method used for drug detection but it is not a very good choice in most of the cases. Nobody can confirm the reliability of this test. Drug identification is done on the basis of the analysis of the depositions at the hair root. But most of the time, such drug testing does not provide a very reliable result. Moreover, washing the hair can result into the loss of evidences and in that case an addicted individual can get clean chit. The chance of contamination is significantly higher. In that case too, the result of hair drug testing may be far from being accurate. That is why many a lab does not use hair as a sample for the test.

The accuracy of the result is not only dependent on the mode of testing but also on the efficiency of the sample collectors and analysts. Even minor mishandling may lead to an inaccurate result. Therefore, it is very much important for the lab technicians to be fully aware of the nitty-gritty of every drug testing method. Proper collection, precise analysis and random notification are three important factors that influence the degree of accuracy of the test result. The clinic where the testing is done must conform to the specified system standard.
