Included Substances
5 substancesCDT (Carbohydrate-Deficient Transferrin), 3-MMC, Amphetamines, Ketamine, Cocaine Metabolite
With this urine drug test, a lab tests your urine for cocaine, ketamine, amphetamine and 3-MMC. A blood draw also measures CDT, a marker of alcohol use over several weeks.
You give both samples at a collection point near you. No test strip at home, but an analysis in an ISO 15189 accredited lab.
Why this test?
You can also buy a drug test at a drugstore. That self-test shows a line per substance: yes or no. A lab measures the concentration of each substance and compares it with a cut-off.
There are several kinds of drug tests: urine, blood, saliva and hair. Urine shows most drugs for longer than blood. According to Jellinek, cocaine shows in blood for up to about 2 days. In urine it often shows for 2 to 5 days.
For alcohol it works the other way round. Alcohol itself shows in urine for 1 to 5 days. CDT in blood says something about drinking over several weeks.
Who is this test for?
This test may suit you if you want certainty about your own use. For example if:
- you want to know which drug still shows after a party
- you are preparing for a job application or assessment that may include drug testing
- you have stopped and want a lab result for your own records
- you do not trust a self-test and want a result per substance
The result is yours. Only you see it in your secure account.
What is tested?
- Cocaine (urine): the lab looks for benzoylecgonine, the breakdown product of cocaine.
- Amphetamine (urine): amphetamine, also known as speed.
- Ketamine (urine): ketamine and the substances your body breaks it down into.
- 3-MMC (urine): a designer drug, also called 3-methylmethcathinone.
- CDT (blood): a change in transferrin, the protein that carries iron. According to alcoholinfo.nl it appears with more than six drinks a day.
What can this test tell you?
For each substance you see whether it was found above the cut-off. A positive result suggests the substance or a breakdown product was in your urine. It says something about use in the days before, not about how much or how often.
How long a substance stays visible differs per substance and per person. According to Jellinek, these are roughly the urine windows:
- cocaine: 2 to 5 days, with heavy or frequent use 7 to 16 days
- amphetamine: 1 to 5 days, longer with frequent use
- ketamine: about 7 days, with frequent use in a lab test 3 weeks to 3 months
- 3-MMC: probably 1 to 3 days
According to alcoholinfo.nl, CDT returns to a normal value after about 3 weeks without alcohol.
How is the sample collected?
You give two samples at a regular collection point, not at home. You hand in urine and a tube of blood is taken for CDT.
After your order we arrange a referral through ZorgDomein. Within 1 business day you receive an email with a barcode. If you order after 17:00 or at the weekend, the next business day counts.
Bring the barcode and a valid ID. Whether you can walk in differs per location. You see this when you choose your location.
When is this test useful?
People choose this urine drug screening at different moments, for example:
- a few days after use, to know whether it still shows
- before an assessment or job application that may include a drug test
- when a self-test gave a positive result and you want a lab result
- during a period without alcohol or drugs, to record it
Choose the moment based on the window per substance. A test long after use may come back negative.
What do the results mean?
For each substance the report says found or not found, with the measured concentration and the cut-off. CDT is reported as a percentage.
A drug test can sometimes give a false positive. According to Jellinek, methylphenidate (Ritalin) can do this for amphetamine, and quinine for cocaine. If you take medication, mention it when you discuss your result.
Discuss a positive result or a high CDT with your GP. They can help decide whether further steps make sense.
Preparation
You do not need to fast. Drink as you normally would. Drinking a lot of water can dilute your urine and make the result less reliable.
Bring the barcode from the ZorgDomein email and a valid ID to the collection point.
What happens after the results?
When your report is ready, you get a notification. You see it in your secure account and can download it as a PDF to share yourself.
The turnaround differs per substance. Our planning after your lab visit is about:
- cocaine and amphetamine: 96 hours
- CDT: 168 hours
- ketamine: 240 hours
- 3-MMC: 300 hours
Every result includes an assessment by a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Frequently asked questions
It depends on the substance and how often you use it. According to Jellinek, cocaine usually shows in urine for 2 to 5 days. Ketamine shows for about 7 days. With heavy or frequent use it can be longer.
A test that looks for drugs or their breakdown products in urine. In this panel a lab measures cocaine, ketamine, amphetamine and 3-MMC against a cut-off.
Usually a few days, depending on the substance. Ketamine can show longer, and frequent use extends most windows. The windows per substance are listed above.
Only when a marker requires it; the test states it. Fasting is: only water after 22:00 the evening before, at least 8 hours. Leave out coffee and tea that morning, and the draw is before 10:00. Water is always allowed.
This screening costs €249,-, blood draw included. No draw costs are added; you pay yourself.
No, and you need not explain anything to your GP. We request a referral through ZorgDomein within one business day; orders after 17:00 or at the weekend count from the next business day. The ZorgDomein email holds a barcode for the draw site. At some draw sites you pick a time on your order page, or we book it.
No. A screening you request yourself falls outside the basic Dutch insurance. You pay it yourself, and it does not affect your deductible (eigen risico).
Count on one business day, because only then is the referral email in; without a referral you cannot go. After that, some draw sites see you in a walk-in session; the rest work by appointment. Each location tells you which.
The barcode from the ZorgDomein email and a valid ID. The barcode can simply be on your phone. No BSN? Then the email has no barcode and you print the referral form from the link in it.
Yes, take it as always, unless your own doctor decided otherwise. Some markers need more preparation, such as no alcohol for 24 hours. That is on the test and in the instructions with your order.
At the draw site you show the barcode and a valid ID, and then blood is taken. That takes about a quarter of an hour.
Yes, every result is assessed by a BIG-registered doctor, who explains the values in your account. Any treatment you discuss with your GP.
An independent, certified laboratory from the Zuivertest network, spread across the whole of the Netherlands. The laboratories also manage the draw sites; Zuivertest does not own them. Reference values can vary between laboratories.
No. The screening does not go through your GP and does not enter your medical record, and your employer receives nothing. Data goes to a healthcare provider only with your written consent and is never sold. Anonymous is not possible: a valid result asks for your name, date of birth and a valid ID.
