Overview of the Test

The Home CDT Test is a finger-prick alcohol blood test that measures carbohydrate-deficient transferrin, often shortened to CDT. CDT is a biomarker that may rise with prolonged or excessive alcohol use.

This private CDT blood test can help assess alcohol use over the previous 2-3 weeks, making it more suitable for longer-term alcohol monitoring than many standard blood or urine alcohol tests that usually reflect shorter periods.

The test may be useful for people preparing for a DVLA medical, legal or workplace requirements, or personal monitoring. Results are delivered securely by email and supervised before being issued.
