Our results show that mean CDT increases with increasing reported alcohol consumption even within the range of alcohol use considered to be nonhazardous. We found significant effects of sex, age, smoking, previous alcohol dependence, body mass index, and diastolic hypertension on the alcohol-CDT dose-response curve.

Does smoking affect CDT test?

A study of serum transferrin glycoform patterns on 1387 subjects has demonstrated that the adjustment of reference intervals for CDT in relation with ethnicity, age, gender, body mass index (BMI), and smoking is not required.

What can affect CDT levels?

Results: There is evidence that %CDT levels are affected by alcohol use, end-stage liver disease, and genetic variants. In addition to these three factors, total CDT levels (CDTect) are also affected by factors that raise transferrin levels such as iron deficiency, chronic illnesses, and menopausal status.
