Legal alcohol testing services

AlphaBiolabs offers you and your clients the most comprehensive legal alcohol testing on the market today. Not only are we the most competitively priced with our Price Match Promise but we have a UK-wide network of sample collectors available.

AlphaBiolabs determines alcohol abuse by detecting two metabolites of alcohol: ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs). These markers of alcohol intake are incorporated into the hair via different routes: EtG via sweat and FAEEs via sebum (an oily substance secreted by glands in the skin).

Performing two different types of hair analysis can assist in building evidence to support the diagnosis of chronic excessive alcohol consumption with a greater degree of certainty. We would also recommend a blood test to detect alcohol biomarkers, in conjunction with clinical assessment, to gain a greater insight into an individual’s alcohol use.

The recommended minimum length of hair for EtG and FAEE tests is a 3 cm section taken from nearest the scalp. This is consistent with the consensus on hair alcohol testing for chronic excessive alcohol consumption published by the Society of Hair Testing (SoHT) in June 2009.

Hair alcohol testing explained

Testing for alcohol in hair works by looking at EtG and FAEE markers. 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 will be contaminated with alcohol. 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.

We understand alcohol testing

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

Our team of scientists have implemented a system that indicates or rules out chronic excessive alcohol consumption.

Once a history of alcohol abuse is established then a treatment programme can be developed with periodic monitoring.

There is a range of information to assist solicitors and individuals in establishing whether their case is eligible for legal aid funding and this can be accessed at the following website (legal aid checker). We recommend you use this as a starting point before embarking on the complex process of applying for legal aid for your alcohol test application.

Blood analysis: liver function test (LFT)

Alcohol can be toxic to the liver. A person who consumes excessive amounts of alcohol will damage their liver and may experience decreased liver function.

A liver function test (LFT) measures various enzymes in the blood that are produced by the liver. An abnormal result indicates a problem with the liver. For example, an elevated aspartate aminotransferase (AST) value is a biochemical indicator of possible alcohol abuse.

We test a panel of five markers including total bilirubin, AST, alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT) to ensure the result is as accurate as possible.

Carbohydrate deficient transferrin (CDT) analysis

Carbohydrate deficient transferrin (CDT) is a widely recognised specific biomarker of chronic alcohol consumption.

In cases where the sample donor is abusing alcohol, an elevated CDT reading is usually seen. In conjunction with an elevated LFT and EtG/FAEE reading, this strongly suggests that the sample donor is abusing alcohol.
