THC-COOH

Markers: THC-COOH

This blood test measures the THC-COOH. THC is a product contained in Cannabis or weed and can be determined as a measure of how long ago someone started using cannabis or weed has smoked. THC is excreted quickly, within a few hours.

What is the difference between THC and THC-COOH?

THC is the psychoactive part of cannabis which makes you 'stoned'. In the liver, THC is converted into THC-COOH within a few hours. This is a metabolite and remains in the blood for longer, a few weeks or even months before it is completely broken down. The breakdown rate differs for everyone, because THC-COOH is stored in fat cells. The more weed you smoke, the longer it takes for all the THC-COOH to be broken down.

Can I request this Cannabis / THC test myself or does a psychiatrist do that?

You can also order this test yourself. However, this is often done by a psychiatrist in the context of a health declaration for the CBR done. The results will then be sent to your requesting psychiatrist. The THC-COOH blood test for the CBR is a new method. Previously, the determination was made in the urine, but the blood test is more accurate.

The results of this test will take 10-15 days. Only if you request the test yourself will the results be sent to you!

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.

    Information on various health topics and a clear overview of our extensive test offerings. Through the website, you can easily determine which test may be relevant for you. Do you need assistance in making a choice or would you like to customize your own package? Feel free to contact us.

    Choose a testing location

    We conduct tests at 350+ locations across the Netherlands, ensuring there is always a location near you. During the ordering process, you can easily select your preferred testing location, and after payment, you can schedule an appointment. Choose where and when it suits you.

    Get tested

    During your appointment, one of our medical professionals will collect your sample. Subsequently, your sample will be examined in the laboratory.

  4. 4

    Truly reliable results with understandable explanations

    Because your sample is taken professionally, the results are consistent. Your test results are evaluated by one of our own doctors and accompanied by thorough advice.

This examination is often requested by a psychiatrist for a health declaration. This examination is requested in the context of a CBR investigation into the fitness to drive of the driver's license holder.
The accuracy of the test for THC-COOH 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 THC-COOH 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 THC-COOH 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 THC-COOH can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for THC-COOH. 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 THC-COOH 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 THC-COOH 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 THC-COOH to third parties without permission, not even to your general practitioner without your consent.
The blood test for THC-COOH 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 THC-COOH 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 THC-COOH 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.
