CDT Alcohol

Markers: CDT, gamma-GT

What is a CDT alcohol test?

When you drink alcohol, it is absorbed into the blood and processed by the liver. The liver can process approximately one drink of beer per hour. When the intake is more than the breakdown per unit time, there may be intoxication. We call this being drunk. A CDT alcohol test can show whether you have consumed alcohol and to a certain extent also how much. This is expressed as a certain percentage in the result. This can be done via a breath test, but also via a blood test. A breath test is only effective for a certain time after alcohol consumption, while a blood test gives an idea of alcohol consumption up to a few weeks earlier This is due to the presence of CDT.

What do we determine with an alcohol test?

With an alcohol test we look at how much CDT is present in the blood. Carbohydrate deficient transferrin (CDT) is a protein that is produced when drinking alcohol. CDT shows what alcohol consumption has been like over the past period. The percentage is higher when alcohol is consumed. If you do not consume alcohol at all for a few weeks, the level usually returns to normal. However, this may take longer with long-term alcohol use.

Can I request this CDT examination myself or does a psychiatrist do that?

You can also do this examination yourself to request. However, this is often done by a psychiatrist in the context of a health declaration for the CBR. The results will then be sent to your requesting psychiatrist. Only if you request this test yourself will the results be sent to you!

The results of this test will take 7-10 days.

How does it work?

Professional testing

Self-tests do not always provide reliable and consistent results. That's why Labplusarts chooses to have the tests professionally administered at a testing location. We have made this process as simple as possible for you.

When to choose a CDT alcohol test?

The CDT blood test is recommended:
  • When you need an explanation for driving ability through the psychiatrist
  • To measure whether alcohol consumption has been reduced and / or resumed

Why an alcohol test?

This test is sometimes mandatory by the CBR when someone has been arrested for driving under the influence. An employer may also want to check alcohol consumption or you may want to know how your CDT value is doing. This research will give you a clear picture of alcohol consumption over a longer period.
The accuracy of the test for CDT Alcohol is conducted through ISO-certified laboratories. The accuracy of a test method is expressed in terms of specificity and sensitivity. However, the most important aspect is that the results are interpreted and accepted among general practitioners and hospitals. This is the case with our venous samples. Mutual acceptance may not always be present due to potentially reduced reliability with a capillary sample.
Most tests generally take 24-48 hours. Tests that go through an LC-MS method generally take longer, think about an average of 3-7 working days. Additionally, it also depends on the location. Some locations do the analysis themselves and others outsource it to another lab.
Interpreting the results of CDT Alcohol is not always easy and should be seen in the broader picture, along with anamnesis and physical examination. In the doctor's advice section, the query in which you can already outline your complaints is taken into account, otherwise, the results are interpreted in conjunction with the other results. If necessary, the doctor can call to ask about physical abnormalities. You don't have to interpret the results yourself because there is always advice and explanation from the doctor.
If the results of the test for CDT Alcohol are clinically significantly abnormal, the doctor will contact you by phone. If you are not reachable, you will receive an email. This includes advice and an explanation of the abnormal results and what you can do about them. If you need a prescription or referral, we can help with that.
The costs of CDT Alcohol can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for CDT Alcohol. For example, tests for IVF treatment are often reimbursed. After your order, you will receive an invoice that you can submit to your insurance.
The ordering process is easy. You can add a CDT Alcohol test or the tests you want to your shopping cart. In step two, you fill in your details and pay. Then you will receive an email confirmation and you can go to a collection location. After you have been there, you will receive the results of the CDT Alcohol test in your Portal.
We are certified-ready according to the NEN 7510 and 7512 standards for secure data transfer in healthcare. The Portal is secured with two-factor authentication. Your data is also encrypted. We do not send the results of CDT Alcohol to third parties without permission, not even to your general practitioner without your consent.
The blood test for CDT Alcohol must take place at one of the collection locations we provide. At certain locations, it is possible for a phlebotomist to come to you. You can indicate this during checkout. An appointment will then be made as soon as possible to come to your home.
You can easily make an appointment for CDT Alcohol blood test after your order in your Portal. You can visit almost daily in all major cities in the Netherlands. In smaller cities, you can visit on certain days. At certain locations, it is also possible to visit on weekends.
An interpretation by a doctor or an explanation is included in the CDT Alcohol test. The explanation takes into account the query that you can specify in your Portal after ordering.
For blood tests, we always use venous sampling. This is the gold standard for blood collection. Over-the-counter tests, such as a finger prick test, use the capillary route for blood collection. These do not always give the same results and the accuracy depends on how, where, and with which technique the collection is done. The advantage, of course, is that the test is easier and less painful to take.
You can always pay with iDeal and credit card (VISA, Mastercard, and Amex). This also includes Apple Pay. The phlebotomists at the collection location cannot accept cash payments.
The results of Labplusarts can be shared with your general practitioner at your request. However, you can also easily arrange this yourself by downloading the result in PDF format. Because we use comparable test methods as the general practitioner, the results are interchangeable and comparable so that comparisons can be made well.
