Clinic significance

This test is used to detect chronic alcoholism. The consumption of 50 to 80 grams of alcohol every day for one week induces a rise in the level of carboxy-deficient transferrin (CDT) (specificity 98%, sensitivity 80%). After withdrawal, the serum CDT concentration drops off again with a half-life of 14 to 17 days.

Prenalytics

• 1 mL
• Non haemolysed serum
• Refrigerated
