Hair drug test example

Hair analysis can not only detect an illegal substance or prescription drug abuse, but it can also present an accurate retrospective record of substance misuse. Hair testing for drug use is a powerful analytical tool to measure the number of drugs and drug metabolites embedded inside the hair shaft. Analysing a small sample from the head or body can establish the level of use over a period of up to 12 months, depending on the length of hair available.

A longer history of intake can be established if necessary, but this will require at least one more sample to be taken at a different time, this is known as segmentation. As the drug metabolites form on hair growing below the scalp, a historical record of substance misuse from hair drug testing will span to a week prior to when the sample was taken.

Hair drug testing is the most comprehensive and effective technique for exposing drug misuse. Sample collectors follow strict procedures to maintain chain of custody and Toxicology experts will assess the reports of the results; only when they are fully satisfied with them is when they will be released to the client, assuring accuracy at every stage of the process.

Our hair drug testing produces an historical record of substance misuse over a period of 1 to 12 months.

Hair Drug Testing FAQ

Below are some of the questions we get asked most about our hair drug testing services.

What time period can a hair drug test cover?

Hair grows at an average rate of 1cm per month. A 3cm section of head hair will provide an approximate time period of 3 months. The time period that a hair sample can cover is dependent on the length of hair that is available. If someone was to have 12cm of hair, then a hair drug test could cover 12 months.

Can body or facial hair be used if no scalp/head hair is present?

If no scalp hair is available, then body hair or facial hair can be used depending on the hair length. Body and facial hair grow at the same average rate of 1cm per month, however it has a different growth cycle to that of scalp hair, meaning that a greater proportion of the hair remains on the body or face in its resting or telogen phase.

For this reason, body or facial hair samples are analysed as a whole sample and we are unable to be segmented into a month by month analysis.

What’s the difference between a month by month analysis and an overview?

A month by month analysis will section the hair into approximate individual months covering the length of the hair that requires analysis. For example, if a hair drug test was to cover 6 months, a month by month analysis will provide 6 individual results for each approximate monthly period. This is especially useful if you need to obtain a trend in drug use, i.e. to see a decrease or increase in drug use over time, or highlight particular months where drugs were or not used.

An overview of a 6 month drug test will provide you with 2 results, one for the first 3 months and a second result for the second 3 months. Therefore the overview analysis will provide a general result of drug use within a 3 month time period, and not to an individual month. An overview analysis is beneficial if you only need to obtain a general indication of drug use or abstinence.

What drugs can you detect?

We are able to detect a wide range of drugs in hair, including the following most commonly abused drugs groups.

  • Alprazolam
  • Amphetamine
  • Methamphetamine
  • Ecstasy (MDMA)
  • Cannabis (THC)
  • CocaineCodeine
  • Diazepam (Valium™)
  • Dihydrocodeine
  • Heroin (6-monoacetylmorphine)
  • Ketamine
  • Mephedrone
  • Methadone
  • Morphine
  • Temazepam
  • Zolpidem
  • GHB
  • Steroids
  • Tramadol

How soon after a drug was taken can it be detected in the hair?

It takes about 2 weeks from the time of drug use to it being able to be detected in the hair. This is due to the time it takes for the hair to grow a sufficient length to be cut and analysed. To detect more recent drug use we recommend an oral fluid drug test that will show up to a maximum of 2-3 days.
