This means that even if your client only has 1cm of head hair, we will still be able to test it for levels of the ethyl glucuronide (EtG) direct biomarker. This can then be reported as excessive use of alcohol, or as a negative result. If the head hair is less than 1cm in length, we can test body hair, fingernails or toenails.
What is head hair alcohol testing?
Hair strand alcohol testing is one of the most effective ways of determining whether an individual has been drinking alcohol in excess for up to 6 months. When used in conjunction with other tests, such as blood alcohol tests, it can help paint a complete picture of a person’s historic alcohol consumption.
Alternative alcohol testing samples
If the length of head hair is less than 1cm, body hair or nails can also be used to test for the presence of EtG.
Due to the slower rate at which body hair grows, body hair (e.g. from the arm, chest or leg) could provide up to a 12-month overview of alcohol use. A nail test for alcohol can show abstinence during an approximate 6-month period for fingernails or 12-month period for toenails, by identifying whether EtG is present in the sample.
Both body hair and nail testing for alcohol should also be supported by one or more blood tests.
Combining hair alcohol testing with blood alcohol tests to give a fuller picture
We strongly recommend combining hair or nail alcohol testing with blood alcohol testing to give a fuller picture. There are 4 blood alcohol tests that can be used for legal purposes, which provide a 4-week overview of alcohol use or pathological changes due to long term excessive alcohol use:
- Phosphatidylethanol (PEth)
- Carbohydrate Deficient Transferrin (CDT)
- Liver Function Test (LFT)
- Mean Corpuscular Volume (MCV)
CDT, LFT and MCV are all indirect biomarkers of alcohol and their presence can be affected by pre-existing medical conditions and medications, among other factors. However, PEth is a far superior test as it is a direct biomarker of alcohol (it possesses the unchanged ethyl group of alcohol in contrast to the indirect blood markers). This means that PEth is only present in the body when alcohol has been consumed and is therefore without doubt the best blood testing option for the most accurate and reliable result.
