Legal alcohol testing for legal professionals, local authorities and members of the public for use in UK courts
We provide the fastest, most cost-effective legal alcohol testing in the UK
We understand alcohol testing
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.
Accredited legal alcohol testing
AlphaBiolabs specialises in alcohol testing. We have worked with solicitors and local authorities for 15 years. Our legal alcohol testing is recognised and admissible to UK courts. We go to great lengths to ensure that our alcohol testing processes are the best available, which is why you can be sure if you take a legal alcohol test with AlphaBiolabs you will get the fastest, most accurate testing available.

Alcohol Testing Methods
Head hair alcohol testing
Testing for alcohol in hair works by looking at 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). Unlike drug testing where the metabolites are absorbed through the root of the hair, when a client consumes alcohol the markers are found along the entire length of the hair. Therefore, it is not possible to segment the hair.
For example, if your client’s hair is tested for a 6-month period, and has not drunk alcohol 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.
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. Biomarker testing in hair can establish a person’s history of alcohol consumption for 3 or 6 months.
Performing both EtG and FAEE analyses 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.
Body hair alcohol testing
If insufficient head hair is available, some types of body hair can also be analysed for alcohol testing. EtG analysis can be performed on hair samples collected from the chest, arm, leg and beard. The timeframe for body hair alcohol testing is more approximate due to the nature of this hair growth. The window of detection is up to a 12-month overview.
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 excessively using 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 chronically and excessively using alcohol.
Mean corpuscular volume (MCV) test
Red blood cells are measured in the mean corpuscular volume (MCV) test. 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. MCV will not always be raised by excessive alcohol use and some unrelated conditions can result in higher MCV levels. For example, the test is less specific for alcohol abuse in patients with conditions that can influence the size of red blood cells, such as vitamin deficiencies, liver disease, underactive thyroid disease and smoking.
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.
Phosphatidylethanol (PEth) test
Phosphatidylethanol (PEth) is the most accurate of the blood alcohol tests. This is because PEth is a direct marker of alcohol, which means that it can only be detected when alcohol has been consumed. It requires ethanol for its production and is formed on the surface of a red blood cell when the alcohol reacts with phosphatidylcholine.
PEth testing can detect chronic and single-drinking episodes. It can also be used to monitor abstinence, drinking behaviour and identify relapse. PEth analysis can also verify whether an individual has changed their pattern of alcohol consumption.
Comprehensive Alcohol Analysis Package
The Comprehensive Alcohol Analysis Package provides the best insight into an individual’s level of alcohol consumption.
It combines hair testing (FAEE and EtG) with blood tests (CDT, LFT and MCV) and also includes a Statement of Witness report and sample collection. PEth testing can also be added for an additional fee.
Nail alcohol testing
Like hair, nails are made from keratin, which is a fibrous protein. As the nail grows, substances can pass from the blood vessels below the nail into the keratin fibres where they become trapped. Biomarkers from alcohol can thus be detected in the nails.
Our nail alcohol testing analyses samples for the EtG marker. These EtG biomarkers become trapped within the keratin fibres along the length of the nail providing a detection period of up to 6 months.
Breath alcohol testing
The person being tested for alcohol use blows into a breath alcohol device, and the results are given as a digital readout. The readout is a number, known as the breath alcohol concentration (BAC), which shows the level of alcohol in the breath at the time the test was taken. It does not measure historical use of alcohol.
AlphaBiolabs can provide a number of devices for breath alcohol testing dependent on your individual needs.
SCRAM Continuous Alcohol Monitoring®
SCRAM Continuous Alcohol Monitoring® (SCRAM CAM®) is an innovative way of testing a participant’s alcohol consumption over a defined period of time. The tamper-proof SCRAM CAM® bracelet is worn on the ankle from 1 day up to as many months as needed. Because of its transdermal method of detection (through the skin) every 30 minutes, 24 hours a day, the non-invasive bracelet provides a comprehensive profile of a participant’s drinking activities throughout the entire day and night.
