We all know that there are different kinds of drug tests and each one of them is used for the same objective – to detect drug users. Depending on the type of drug test, a biological specimen (urine, blood, saliva, sweat, or hair) is technically analyzed to detect the presence of drugs or their metabolites.
All drug tests are initiated with one particular step: make the specimen testable. For some of the drug tests, urine or saliva can be used in its unaltered, presently existing condition. For other tests, however, there is a need to extract the drugs from the specimens in advance. If you want to have any type of Drug test you can visit this website- http://lincolndiagnostic.com/.
In most of the drug testing methods, a person’s blood is used as the sample for drug identification. But for more accuracy of the result, it is recommended to use urine in place of blood. But the urine drug test is more expensive.
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.
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.
