Test Details

Testing by CLIA approved lab: LabCorp or Quest Diagnostics

Transferrin is a protein found in the serum that carries iron through the bloodstream to the bone marrow, liver and spleen. There are numerous types of transferrin with the most common form having four sialic acid chains, known as tetrasialotransferrin. In individuals who consume large quantities of alcohol, the amount of transferrin with zero, one or two sialic acid chains increases, known as CDT. This is what is then measured in the bloodstream to be used as markers of alcohol abuse. This test may also be used to monitor treatment in individuals with alcohol abuse and to monitor for a possible relapse.

This test is not intended to detect occasional or light alcohol consumption. Elevated CDT levels are typically indicative of heavy alcohol consumption during the last 2-4 weeks. An ETG Alcohol test may be more effective at detecting alcohol use in the past 1-3 days.
