Information on Hair Sample Testing

Drug testing and in particular hair drug testing is becoming much more commonplace, particularly in the US, UK and the EU. This approach to drug testing has a significant advantage over other detection methods such as saliva, urine and blood, in that it provides a far wider timeframe for which drugs can be detected. (Referred to as the detection window). It is possible to detect drugs for several months – even years if the hair has been allowed to grow for that long. Most commonly however, tests require 90 day detection: This compares to typically 4-5 days for fluid based testing (or in chronic cases of marijuana misuse, one month)

Approximately fifty hair follicles are needed for successful drug hair testing. This is about the thickness of the end of a shoelace, meaning that most people would show no obvious signs that any hair had been removed unless their hair is particularly short.

The cost of hair testing is higher than urine based tests – which are the only other genuine method of achieving top-quality test results. Testing blood samples is not widely available partly due to the difficulties in taking a sample in the first instance.

A typical hair sample test costs in the region of £60-£70 for preparation of the sample (which involves turning the hair from a solid to a liquid) and then an additional £40-50 per drug type required for detection. This contrasts to an approximate charge of £60-75 for laboratory testing of urine which will pick up illegal substances across all drug classes.

One of the most common questions how to pass a hair drug test. Very simply, there is only one sure-fire way in which to guarantee this – Don’t take drugs!
