Ordered my Home CDT test online and sent my sample to the lab. Results to my inbox. Couldn't have been easier! Robert P.
A CDT (Carbohydrate-Deficient Transferrin) test measures alcohol misuse markers in your blood. Elevated levels can indicate prolonged excessive alcohol consumption.
You may need a CDT test to prepare for a DVLA medical after a drink-driving ban, ensure you meet fitness-to-drive standards, or confirm reduced alcohol intake over time.
The CDT test involves drawing a small blood sample. A laboratory then analyses the sample to detect changes in transferrin protein due to heavy alcohol use.
Avoid excessive alcohol for several weeks before testing. Eating a balanced diet and staying hydrated can also support more accurate results.
