Drug Testing Information

Blood Drug Testing is rarely used because it is much more expensive to test a person's blood for drugs, and to collect blood requires a medically trained nurse or other certified medical expert. Blood drug testing is very accurate however. This is because it is not like most drug tests, because it looks for the actual drugs in a person's blood, not the metabolites of the drugs. This makes it very difficult for a person who has used drugs to pass a drug test or cheat a drug test.

Blood Drug Tests are usually performed during autopsies after a person has died, or when a person has overdosed and is unconsciounce. It's not cost efficient for employers to use them, so it is very rare for an employer to consider using a blood drug test to test their employees.
