How much does a hair drug test cost?
What is hair drug testing?
A hair drug test is used to analyse samples of hair, originating from the head or body, for the presence of drugs and their metabolites (breakdown products).
Upon consumption, drugs enter the bloodstream. Through the bloodstream, the parent drug and its metabolites travel to the hair follicles, where they are deposited and remain within the hair shaft as it grows.
Therefore, when the hair is analysed by the toxicology laboratory, the parent drug and/or its metabolites will be identified within the hair.
How does hair drug testing work?
Hair drug testing can be used to examine cut hair samples for the presence of drugs and drug metabolites.
When a person ingests drugs, the drug and/or its metabolites enter the bloodstream, and as a result their hair follicles. The drugs become entrapped within the innermost layer of the hair shaft known as the medulla. A toxicology laboratory can then detect drugs within a cut hair sample for a period of up to 12 months.
A month-by-month pattern of drug use can be determined by considering the following two statistics:
- it takes 7-10 days for hair to grow above the surface of the scalp
- head hair grows at an average rate of 1 cm per month
There are two methods available for head hair drug testing: segmented analysis, and overview analysis.
Segmented analysis is the most detailed form of hair strand testing for drugs. The collected hair sample is separated into 1 cm segments that are then analysed to provide a detailed month-by-month history of drug use. As a result, segmented analysis is particularly helpful for identifying trends in drug use, such as intermittent use, or the increase and/or decrease of drug consumption over time.
Segmented analysis can be used to identify patterns in drug use for a period of up to 12 months.
On the other hand, overview analysis provides a more general insight into a person’s drug use. The hair sample collected will be analysed to obtain an overview of drug use that is averaged out over the selected time period.
The maximum length of hair that can be tested to provide an overview of drug use is 3 cm, which provides an overview of three months.
The maximum overview period that can be provided is 12 months, which will be shown as 4 x 3-month overviews.
It is important to consider that in a hair strand overview test, an individual could test positive if they have abstained from drugs for 2 out of the 3 months, but ingested drugs within the other month, as the result is calculated as an average consumption over the defined period.
How much does a hair drug test cost?
The cost of a hair strand drug test depends on the exact testing requirements, and will vary on a case-by-case basis.
The key factors that will influence the cost are:
- The number of drugs being tested for
- The time period of analysis required
- Whether the test is a segmented or an overview analysis
