Testing for PEth, liver function and CDT

When used alongside hair testing, blood alcohol testing can help to provide a comprehensive view of chronic excessive alcohol use. We offer blood tests for phosphatidylethanol (PEth), liver function testing (LFT) and carbohydrate deficient transferrin (CDT).

For phosphatidylethanol (PEth) testing, we offer two forms of collection: venous and dried blood spot. The latter is perfect for needle-phobic donors as only a small prick to the finger is required and collection takes less than two minutes.

No single test is able to provide a definitive assessment of alcohol use and so we recommend that hair alcohol testing is used in conjunction with either PEth or CDT and LFT blood tests.

3. Alcohol Testing
Assessing Chronic Excessive Alcohol Use
Please Select the Sample Type Required for Alcohol Analysis:(Required)
Our hair alcohol test is ISO 17025 UKAS accredited and in accordance with the Consensus of the Society of Hair Testing on hair testing for chronic excessive alcohol consumption. We recommend that hair alcohol testing is used in conjunction with either Carbohydrate Deficient Transferrin (CDT) and Liver Function (LF) or Phosphatidylethanol (PEth) blood tests.
3.1. Please Select the Hair Type Required for Alcohol Analysis:(Required)
As you have selected Body Hair, sections 3.1.1 is not required.
3.1.1. Hair Alcohol Testing:
Hair alcohol test for chronic excessive alcohol consumption. The hair alcohol marker analysis is only undertaken as an overview analysis.

3.2. Blood Alcohol Testing:(Required)
- Select All
- Carbohydrate Deficient Transferrin (CDT) Test
- Liver Function (LF) Test
- Phosphatidylethanol (PEth) Test
- MCV
The blood test for alcohol can be used to indicate recent excessive alcohol use. A CDT test is a biochemical test that can provide biochemical evidence of recent excessive alcohol consumption. A liver function test provides a snap shot in time of liver health damage that may have come from excessive alcohol consumption. A PEth blood test measures the level of phosphatidylethanol, a direct alcohol biomarker which is found in human blood following alcohol consumption. MCV (Mean Corpuscular Volume) is a value that indicates the average size of red blood cells within a blood sample. This blood test can provide indication of recent excessive alcohol use.

Blood alcohol testing explained

Phosphatidyethanol (PEth)
PEth is a direct biomarker found in red blood cell membranes following alcohol consumption. This test isn’t affected by medication or health problems and provides a detection period of up to four weeks prior to sample collection. For needle-phobic donors, we offer dried blood spot testing, which only requires a small prick to the finger.

Liver function testing (LFT)
A liver function test provides a snapshot of potential liver damage due to excessive alcohol use by monitoring biomarkers in the blood stream. Any damage to the liver alters the biomarkers in the blood stream allowing any impairment to be highlighted.

Carbohydrate deficient transferrin test (CDT)
CDT measures the percentage of the protein transferrin that is deficient in carbohydrate. Alcohol consumption can interfere with the binding of carbohydrate molecules to transferrin and so excessive alcohol use two to four weeks prior to the test can elevate levels of transferrin that is deficient in carbohydrate, making it a good marker to assess alcohol consumption.
