What method is used in the CDT test?

Question from Tom: I recently had blood tested by your company.
I received the results and spoke to another doctor about them and their interpretation.
However, I still have 1 question that the doctor did not have an immediate answer to, which is: what method did you use in determining CDT?
Indeed, I do not find the cut-off point of 1.3% (as in your result) anywhere in the method recognized by CBR.
So can you tell me whatmethod you used?

Answer:
Indeed, we use a different method than the CBR usually uses, so we work with different reference values.
namely:
Capillary electrophoresis method.

Reference Value
An increase in CDT is to be expected with daily alcohol consumption of more than about 60-80 g for about two weeks.
The half-life after alcohol is about 14 days.
At the indicated affinity value, a sensitivity of approximately 75% is achieved with a specificity of 98% for increased alcohol consumption.

p.s. Elevated CDT values can also be found at:
CDG syndrome, primary biliary cirrhosis, transferrin D variants, chronic active hepatitis, hepatocellular carcinoma, occasionally postmenopausal, with estrogen therapy and during pregnancy.
