This UKAS 17025 accredited Hair Alcohol laboratory test provides an accurate analysis of longer term alcohol intake for upto 6 months.
As hair grows, it absorbs the metabolites of alcohol, Fatty Acid Ethyl Esters (FAEEs) and Ethyl Glucuronide (EtG) into its structure.
A Hair test will look at the amount of each metabolite found in the hair sample, to indicate the level of alcohol consumption for the required time period, up to the previous 6 months.
The FAEE finds its way into the hair mainly by diffusion from an external sebum layer. This is an oily substance secreted by glands in the skin.
Long term excessive consumption of alcohol would cause an elevated FAEE result, if the amount of FAEE detected in the hair sample is above the cut off level of 750pg/mg (picogram per milligram), this suggests that alcohol has been consumed at a chronic level.
The FAEE is used alongside the EtG analysis to give the best overview of a person’s alcohol consumption, as both can be affected by environmental factors. EtG is formed in the liver, and is only produced when alcohol has been consumed, the EtG is then deposited into the hair mainly from sweat.
A higher level of EtG being detected in the hair illustrates that more alcohol has been consumed, the reporting guidelines are as follows:
Example of EtG Interpretation
If the EtG is lower than 7pg/mg, this is suggestive of abstinence within the period covered by the sample.
If the EtG is between 7 – 30pg/mg, this is indicative of alcohol use within the period covered by the sample.
If the EtG is over 30pg/mg, this is suggestive of chronic excessive alcohol use within the period covered by the sample.
Each Drug Test Donor is legally identified at the appointment. hair samples are then collected, sealed and bar coded to strict Chain of Custody Protocols by a fully trained & certified sample collection officer. Samples are then processed to our UKAS 17025 and ILAC accredited laboratory, where the test is performed.
The test is available at selected Crystal Health network of UK Drug Testing Clinics or via the mobile collection service.
The analysis for a Hair test takes 3 – 5 working days from receipt of your sample.
The fully accredited sample collection process and laboratory analysis ensures that all test reports issued are legally defensible.
It is recommended that a Blood Alcohol test is performed in combination with the Hair test to give the most accurate analysis of a person’s alcohol consumption.
We also recommended that an Expert Witness statement is requested to give a further understanding of the test report, this can be discussed at the time of your booking.
All administration including the test results process is performed in compliance with ISO 9001, ISO 27001 and ISO 14001.
Why and when would you use this alcohol test?
The Hair test will verify if a person has been abstinent from alcohol; or if they have been consuming alcohol that has not been at a chronic excessive level.
Hair testing is a requirement in many legal cases and can also be used for personal information.
We are able to indicate the level of alcohol use for up to 6 months with the Hair test, this can be to provide evidence of abstinence or show that alcohol is not being abused.
1cm of head hair will show approximately 1 month of alcohol use, however as per the Society of Hair Testing (SoHT) guidelines, it is recommended that either 3cm or 6cm of hair is tested.
Body hair from certain areas can be used if a head hair sample is not sufficient for the required analysis, however, the time period shown by a 1cm body hair sample is 2 to 3 times longer. Back hair and underarm hair cannot be used. However, pubic hair can be used only to prove abstinence but not to disprove accusations of abuse.
