Also to know is, what is a normal CDT result?
In heterozygous, or carriers of the disease, CDT levels are variable but typically are in the range 10-25%. 3) Level of alcohol consumption necessary and over what period to increase the CDT level to 3.0%. Typically the level of alcohol intake required to produce a CDT result of 3.0% is 100-150 g alcohol/day.
Also know, what does a CDT test show?
Carbohydrate-deficient transferrin, known as “%CDT,” is a blood test to detect heavy alcohol use (five or more drinks a day) over the past two weeks. 1 This alcohol biomarker can provide clinicians with an objective way to screen and monitor clients in treatment for alcohol use disorders.
Alcohol misuse is the most common reason for increased CDT levels and in most studies carried out on persons who are potentially misusing alcohol, the test has 95% specificity i.e. 19 out of 20 times the increased CDT levels are a result of excessive alcohol consumption.
