What is involved in the drug test?

Drug test or toxicological test identifies the presence of illegal drugs such as cocaine, heroin and cannabis, as well as legal drugs such as alcohol or nicotine. Urine or blood samples are often used for drug tests. These tests can be carried out for many reasons, and people who are preparing for drug tests should be aware of what factors can affect the results of the drug results.

Toxicological tests can be used to isolation of a number of drugs, either by identifying the substances themselves or their metabolites that are materials created on the body metabolizing the compound. In the US, these tests are usually performed on blood or urine samples, although sometimes hair, saliva, tissue or even sweat can be used. For the United Kingdom and Canada, hair was used in courts as evidence of illegal use of drugs. According to some sources, the substances can remain in the hair for a remarkably long time and are often not affected by hair dyes and other hair products.

Blood samples areykle pumped from the arm. The most accurate urine samples for the drug test are pure samples in the middle of the current. Sometimes the urine temperature is taken to ensure that it comes from a real person that is projected.

The

person who takes the drug screen should provide a list of prescription drugs and over -the -counter medicines, including cold drugs and nutritional and herbal supplements that he usually takes. These substances may sometimes affect the result of the drug test. For example, before 1998, Ibuprofen could bring a false positive result in drug tests, although more specific drug tests have repaired this problem. Some argue that poppy seed consumption can generate false positive results, although others claim that dozens of poppy bags would have to be consumed to happen. Being on a safe side is probably the best to avoid poppies before the drug test.

Tests may be required for different purposespharmaceuticals. For example, they are often used by companies to examine potential and current employees and are used in sports to detect steroids in athletes. Insurance companies can order both clients and urinary tests to assess the presence of illegal drugs or legal drugs such as nicotine or alcohol. For forensic purposes, drug tests can also be used, as in the autopsy or to detect the use of the drug for rape.
