Carbohydrate Deficient Transferrin (CDT) DVLA Blood Test
Is it for you?
- Alcohol Consumption
Alcohol Consumption (1 Biomarker)
From the expert
Intermittent or binge drinking can also increase CDT levels. The extent to which this occurs is dependent on the frequency of binges and the amount of alcohol consumed on each occasion. Elevated CDT will decline with reduced alcohol consumption and will revert to normal after several weeks of abstinence.
This test has a very high level of specificity (i.e. it is not affected by other drugs or substances) and therefore it has been adopted by the Secretary of State's Honorary Medical Advisory Panel as the sole test for assessing harmful use of alcohol for high risk offenders.
