About this test

This blood test for Carbohydrate Deficient Transferrin (CDT) enables evaluation of recent alcohol intake, either for initial assessment or to monitor levels of consumption.

High consumption of alcohol up to 2-3 weeks prior to submitting the sample will lead to a high CDT percentage figure.

If you have lost your licence because of a drink driving offence this test result may be requested by the DVLA as evidence of low alcohol intake.
