Carbohydrate Deficient Transferrin (CDT) DVLA Blood Test

CDT Blood Test DVLA – Alcohol Biomarker Test for Driving License Reinstatement

Essential Alcohol Testing for DVLA Requirements

If you are required by the DVLA to provide evidence of alcohol consumption levels, the CDT Blood Test (Carbohydrate Deficient Transferrin Test) is a key screening tool used to assess chronic alcohol consumption over time. This test helps determine whether an individual has been consuming excessive amounts of alcohol in the weeks leading up to the test.

A high CDT level may indicate excessive alcohol consumption, while a normal or low CDT level suggests moderate or no significant alcohol intake. The DVLA may request this test if you are applying to reinstate your driving license after a ban related to alcohol misuse or as part of ongoing medical assessments for fitness to drive.

What This Test Measures

This Carbohydrate Deficient Transferrin (CDT) Blood Test evaluates:

✔ CDT Levels (Carbohydrate Deficient Transferrin) – CDT is a biomarker used to detect chronic excessive alcohol consumption.
✔ Alcohol-Related Biomarkers – High levels of CDT in the blood can indicate heavy alcohol use over the previous 2-4 weeks.

This test is primarily requested by the DVLA for medical fitness-to-drive assessments but may also be used by employers, legal cases, and personal monitoring.

Why CDT Testing is Important for DVLA Medical Licensing

The DVLA mandates CDT blood testing in certain cases to assess whether an individual is medically fit to drive. If you have had a driving disqualification due to alcohol misuse, you may be required to prove that you are not engaging in heavy drinking before getting your license reinstated.

This test is one of the most reliable indicators of long-term alcohol consumption, making it an essential part of DVLA alcohol screening policies. Regular alcohol consumption does not always result in high CDT levels, but binge drinking or excessive alcohol intake over time can lead to elevated results.

Understanding your CDT levels can help you manage your alcohol intake, track recovery progress, and meet medical licensing requirements.
