This UKAS 17025 accredited Hair Alcohol laboratory test provides an accurate analysis of longer term alcohol intake for upto 6 months.
As hair grows alcohol markers such as Fatty Acid Ethyl Esters (FAEEs) and Ethyl Glucuronide (EtG) can be absorbed and bound into the hair strand.
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 would indicate that more alcohol has been consumed, the reporting guidelines are as follows:
EtG lower than 7pg/mg= suggestive of abstinence
EtG between 7 – 30pg/mg = suggestive of alcohol use.
EtG higher than 30pg/mg = suggestive of chronic excessive alcohol use
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.
This test is available at selected Crystal Health 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 picture 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.
