CDT (CARBOHYDRATE DEFICIENT TRANSFERRIN)

CDT (Carbohydrate Deficient Transferrin) is a blood-based biomarker that detects abnormal transferrin glycoforms associated with sustained heavy alcohol consumption. The test measures the relative amount of carbohydrate-deficient transferrin isoforms in serum, providing an objective indicator of chronic alcohol exposure over the preceding 2–3 weeks rather than a single drinking episode.

CDT testing is useful for clinical monitoring, workplace or medico-legal screening, and evaluation of patients with suspected alcohol-related liver disease. Touch Connect offers home blood collection by certified phlebotomists across Dubai and the UAE with fast, reliable laboratory processing and clear results suitable for clinicians, treatment programs, or personal monitoring.

Sample collection is by venous blood draw; fasting is not required. Results should be interpreted in clinical context — factors such as recent transfusions, certain liver or congenital glycosylation disorders, pregnancy, and rare transferrin genetic variants can affect CDT levels. Always review results with a qualified healthcare professional for diagnosis or treatment decisions.
