Description
An official test used to track heavy long-term alcohol consumption. When alcohol is consumed steadily and heavily (4-6 units of alcohol per day) for several weeks, the CDT % increases, and this continues if you continuously drink heavily.
Occasional or binge drinking also raises CDT levels, depending on how often and how much is consumed. Reducing alcohol consumption results in a drop in CDT levels, which normalise in a few weeks. This test is very specific, meaning that it is not affected by other substances. Authorities use it as an official test to evaluate harmful alcohol use.
