Alcohol CDT Blood Test measures the amount of CDT, or Carbohydrate-deficient Transferrin, in a person's blood. Transferrin is a protein whose job is to transport iron through the blood. Various type of Transferrins exist and CDT is a type of Transferrins found in people who drink alcohol a lot.
When CDT is elevated, it usually means the person has consumed a lot of alcohol in the past 2 to 4 weeks.
CDT testing is used to identity alcohol abusers. The test does not detect light or occasional use of alcohol. If you want to detect alcohol use in the past 1-3 days, ETG Alcohol test is more effective.
CDT testing can be an effective tool for the early diagnosis of chronic alcohol misuse, for the detection of patients addicted to alcohol, and for the follow-up of treatment and diagnosis of alcohol relapse.
CDT quantitation is useful in detecting abusive alcohol consumption (defined as ethanol consumption >40 mL per day for at least two weeks) and a more specific marker for alcohol exposure than other available markers, such as γ-glutamyl transferase (GGT). It enables early detection of alcohol misuses and follow-up of alcoholic patients.
On stopping alcohol consumption, the CDT level goes back to normal after two to four weeks. If the patient starts drinking after withdrawal, CDT increases in a few days.
