Hair drug tests

Hair tests are the most useful form of doing a drug test. Hair testing can be used to identify persistent drug misusers. Although Hair testing can be pricey, it is a very accurate form of drug testing. The requirement for a hair test has steadily heightened in recent years and is generally used and recognized by the UK courts.

Hair drug testing not only identifies the existance of a illegal drug, but it can also accommodate an accurate historical record of drug use. This helps in distinguishing between a one-off user and a routine substance abuser, it can also help to monitor abstinance.

Obtaining a small sample of hair cut from the scalp, about 50 strands or the width of a shoe lace, hair tests assesses the number of drug metabolites embedded inside the hair shaft, and can tell you in what time period the drugs were taken.

How Does Hair Drug Testing Differentiate from Other Drugs Tests?

In comparison to more traditional types of drugs testing (i.e, urine drug testing), hair drug testing can expose a greater time frame of drug use. With alternative drug tests, drugs are undetectable after just a small time frame.

With hair drug tests, the only possible problem for exposing drug usage is the length of the donor’s hair. Every half inch of hair in length gives us a 30-day history of drug use.

Overall, hair testing is best to use when trying to establish the time frame of drug abuse and to get a test that will stand up in court. It has both advantages and disadvantages including being very accurate but expensive, it stands up in court but it only tests for one drug per payment. There are many companies that specialise in drug testing, who would be more than happy to give advice on hair testing, any drug tests or queries about drug testing or drugs in general.
