The Carbohydrate Deficient Transferrin (CDT) test is a particularly sensitive biomarker that tracks heavy alcohol consumption over an extended period of time. If an individual drinks steadily and heavily (4-6 units of alcohol per day) for several weeks the percentage of transferrin which is deficient in carbohydrate will rise. The longer a person drinks at this level, the higher the level of CDT. 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 CTD will decline with reduced alcohol consumption, and will revert to normal after several weeks of abstinence.
This test has a very high level of specitivity (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.
This test is for people who wish to prove that they have moderated or ceased their alcohol consumption. It is used by motorists who have been deemed high risk offenders to gain peace of mind before they take a CDT test as part of the DVLA medical examination to get their driving license back.
