Types of hair drug tests
There are two types of hair drug tests available: overview or segmented analysis. As head hair grows, at an average rate of 1 cm every four weeks, drug use can be established over a defined period depending on the length of hair selected. An overview analysis is beneficial to ascertain a general indication of drug use. This could range from 3 cm to identify drug use within that 3-month time period, up to 6 (2 x 3) or even 12 (4 x 3) months, depending on the length of hair available. Differing results from the 3-month overviews can help highlight patterns in drug use.
How is a sample taken?
Around 200 individual strands of hair need to be collected from a discreet area. Hair samples are usually taken from a person’s head; however, if head hair is not available alternative collection sites could be considered including underarm, chest, leg and beard hair.
