Project Description
CDT test
As part of a driving test, do you wish to demonstrate that you do not drinking anymore?
Do you need to undergo an evaluation as part of a conditional driving ban or for insurance institutions?
Persons wishing to request a review or lifting of driving bans (Article 44 Road Traffic Act) must add the necessary supporting documents to their file. In cases of (problematic) alcohol use or alcohol addiction, repeated consecutive results of specialized blood tests, such as Carbohydrate Deficient Transferrin – CDT for short – traditionally play an important role.
The marker CDT is an indirect biological marker, which can still be requested by the judiciary to prove that you are no longer consuming alcohol.
The test is done on blood, you do not need to be sober for this and the full result is known within 8 working days.

Following parameters are determined at the CDT medicolegal panel:
CDT
More info on these parameters:
CDT, like MCV and gamma-glutamyl transferase (γ-GT), is an indirect marker for alcohol consumption: under the influence of ethanol and the metabolite acetaldehyde, isoforms of transferrin are formed with 1 or both carbohydrate chains missing = carbohydrate-deficient transferrin (CDT).
The CDT test reflects a person’s alcohol use over the past two to three weeks and is used by insurance agencies, the judiciary, among others, to estimate a person’s (chronic) alcohol use.
The amount of CDT in the blood increases with excessive alcohol consumption over a period of at least a week. From a consumption level of one or two glasses per day, we see an increase in the percentage of CDT as more alcohol is consumed. CDT is primarily increased in chronic alcohol consumption, in contrast to binge drinkers, where CDT seems to increase rather moderately. To cause a significant increase in CDT, frequent/daily intake of > 60 g of alcohol (cfr. 1 bottle of wine or 1.5 liters of beer/day) is necessary for 2 weeks or more. With abstinence, CDT usually falls to normal within two to three weeks, but after prolonged alcohol consumption, this normalization may take much longer.
By determining CDT in blood (and at different consecutive times), a person can demonstrate that he or she has not consumed alcohol excessively over an entire period of time.
