Hair drug tests
A hair drug test is the most effective way of carrying out a drug test. Hair drug tests are used to determine regular substance users. Although Hair drug tests can be pricey, it is a very accurate form of drug testing. The demand for a hair test has steadily elevated in recent years and is popularly used and autherised by the UK courts.
Hair follicle drug testing not only ascertains the presence of a illegal drug, but it can also accommodate an accurate record of substance abuse. This aides in differentiating between a one-off user and a chronic substance misuser, it can also help to monitor abstinance.
Using a small lock of hair pulled from the scalp, about 50 strands or the width of a small pencil, hair follicle testing assesses the number of drug metabolites found inside the hair shaft, and can tell you in what time period the drugs were taken.
How Does Hair Follicle Drug Testing Differentiate from Other Drugs Tests?
In comparison to different forms of drug testing (i.e, urine drug testing), a hair drug test can expose a longer time frame of drug use. With these other drug tests, drugs are only detectable for a small time frame.
With hair follicle drug testing, the only issue for discovering drug usage is the length of the donor’s hair. Every half inch of hair in length shows a 30-day history of drug abuse.
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.
