“I use AlphaBiolabs every time for my client’s legal alcohol testing. That way I know my results are correct”
David Brown, Family Law Solicitor

Legal alcohol testing for legal professionals, local authorities and members of the public

We provide the fastest, most cost-effective legal alcohol testing

Legal alcohol testing services

Alcohol abuse can be detected in hair by testing for two different alcohol metabolites. The first metabolite is ethyl glucuronide (EtG) and is present on the outside of a person’s hair shaft. The second metabolite is fatty acid ethyl ester (FAEE) and is found on the inside of a hair shaft. By performing both tests the evidence is strengthened to determine whether alcohol has been chronically abused.

We would also recommend three additional tests for alcohol using blood samples to gain a greater insight into an individual’s alcohol use. These are a liver function test (LFT), a carbohydrate deficient transferrin (CDT) test and a mean corpuscular volume (MCV) test.

Hair alcohol testing explained

According to the Society of Hair Testers, the minimum length of hair required for an EtG and FAEE analysis is 3 cm from nearest the scalp (proximal). Both of these alcohol markers are absorbed into the hair via sweat and diffusion.

Unlike drug testing where the metabolites are absorbed through the root of the hair, when a client consumes alcohol the entire length of the hair is contaminated. Therefore, it is not possible to segment the hair. For example, if your client had not drunk for 5 months and then in 1 month drinks an excessive amount of alcohol, the alcohol markers will be found throughout the entire length of the hair.

Biomarker testing in hair can establish a person’s history of alcohol consumption for up to 6 months.

We understand alcohol testing

AlphaBiolabs offers you and your clients the most comprehensive legal alcohol testing on the market today. We are the most competitively priced with our Price Match Promise and have a network of sample collectors at the ready.

Our expert scientists employ a system that indicates or rules out chronic excessive alcohol consumption. It is possible that the FAEE / EtG results may be inconclusive. Therefore, we always recommend that a blood sample be taken to complement the hair alcohol test.

Blood analysis: liver function test (LFT)

Alcohol in sufficient quantities can be toxic to the liver. An individual who chronically abuses alcohol may experience cirrhosis of the liver leading to reduced function or, in the most extreme cases, death.

A liver function test will test for liver enzymes in the blood, which strongly indicate damage to the liver. Our liver function tests include five markers: total bilirubin, aspartarte aminotransferase (AST), alanine aminotransferase (ALT) and Gamma glutamyl transferase (GGT).

Carbohydrate deficient transferrin (CDT) analysis

A carbohydrate deficient transferrin test is widely used as a measure of chronic moderate-to-heavy alcohol consumption. A simple blood sample will provide information to determine whether alcohol has been chronically abused in the preceding 4 weeks.

In cases of chronic alcohol abuse, the CDT value will become elevated to a value outside of the normal range. Paired with increased LFT values, and elevated EtG and FAEE results, the evidence will provide conclusive support for chronic alcohol abuse, or indeed abstinence if the results are within the normal range.

Mean corpuscular volume (MCV) test

The mean corpuscular volume (MCV) test measures red blood cells. An MCV marker higher than normal would indicate an enlarged blood cell, which could indicate ingested alcohol. Elevated MCV is common in alcoholics. This change results directly from the effect of alcohol on red blood cell development and persists as long as drinking continues.

MCV is not a liver enzyme and is influenced by different factors to LFT and CDT. As a stand-alone alcohol abuse indicator MCV has somewhat low sensitivity. However, when combined with the other blood markers it becomes a good indicator for excessive drinking.
