can diabetes affect the results of a cdt test? i'd ...

Other published causes of an elevated CDT (carbohydrate-deficient transferrin) test, besides chronic alcohol abuse, include biliary cirrhosis and obstructive liver disease. These two disorders effect the liver directly, the organ than is responsible for the production of CDT. I was unable to find any published link between abnormal blood sugars, insulin levels or diabetes and an abnormal test result.

The test can detect a single episode of heavier than normal alcohol use, so perhaps 4-5 drinks in a single day. But other than the above mentioned exceptions, I know of no link between diabetes and an abnormal CDT result.

I hope that this helps. Please let me know if you have any further questions. Take care

thanks for my reply. i had thought that as the test involved carbohydrate levels, the lack of carbohydrates at the time may have affected it?

It doesn't really involve carbohydrate levels, per se, instead it measures a specific carbohydrate that is attached to a protein (manufactured by the liver) that circulates in the blood. People who are chronic alcohol "abusers" (so who consume at levels beyond what is considered "normal") will also have borderline abnormal liver function that will effect the production of this carbohydrate. But carbohydrates otherwise, as a family of food types, are otherwise unrelated to the CDT test.

Take care
