What is THC?

Tetrahydrocannabinol (THC) is the primary psychoactive component found in cannabis. It is the substance responsible for most of the psychological effects of marihuana, including the feeling of being 'high'.

Why should you test for THC?

Testing for THC can be helpful for individuals who want to understand how much THC their body contains, especially in contexts where legal limits apply (such as driving, workplace testing, etc.), or for medical patients who want to optimize their dosage.

What does it indicate?

THC levels in urine provide an indication of recent cannabis use. It can help in determining the frequency and quantity of use.

What does a high THC level mean?

A high level of THC in the urine indicates recent, frequent, or intensive cannabis use. This may point to potential misuse or exposure to high doses for medical users.

What does a low THC level mean?

A low THC level may indicate occasional use or declining THC levels following a period of abstinence. It may also suggest a body that metabolizes THC efficiently.

Indication-specific evidence

This test has clinical value for specific complaints or indications, but is not intended as screening without symptoms.

Rationale for this test

Deze test detecteert THC-metabolieten in urine en is een gevestigde methode om recent cannabisgebruik aan te tonen. De test wordt in Nederland gebruikt in specifieke contexten zoals rijgeschiktheidskeuringen, werkplektests en verslavingszorg. De test is echter niet geschikt als algemene screening zonder duidelijke indicatie, omdat een positieve uitslag alleen recent gebruik aantoont maar geen onderscheid maakt tussen licht en zwaar gebruik, en geen uitspraak doet over actuele beïnvloeding of gezondheidsrisico's.

Frequently asked questions

Answers to what people usually want to know.

See urine instructionsFull instructions with visual guidance
How does the urine test work from A to Z?

After ordering we ship the collection kit to your home. You collect urine following the instructions, return it in the envelope, and receive your result digitally by email.

How do I collect my urine sample correctly?

Follow the included instructions, usually the midstream method in a sterile container. Pay attention to the right timing (first morning urine or random, depending on the test).

Do I need to avoid anything before collection?

For some tests yes (e.g. certain foods or supplements). Whether this applies is stated in the instructions. Read them before you start.

When and how do I receive my result?

Usually 2 to 5 working days after the lab receives your sample. You get an email with a link to your digital result, including explanation per value.

How do I return my sample to the lab?

In the included return envelope with free medical shipping. Drop it in the mailbox; the lab processes your sample as soon as it arrives. For some tests it's important to send it the same day — the instructions make this clear.

What if I have questions or something doesn't work?

Feel free to contact us via WhatsApp, email or phone. We're happy to help you before, during or after your test. If the collection doesn't work, we'll arrange a solution or send new materials — no hassle.

“Hele fijne en snelle service”

Hele fijne en snelle service! Ik contacteerde ze ‘s nachts omdat ik zsm moest bloedprikken, ik kon die ochtend nog terecht en heb dezelfde dag mijn uitslag binnengekregen. Echt top!!

“Bloedcheckup levert”

JoaquinVerified

“Klantenservice was erg behulpzaam in…”

Klantenservice was erg behulpzaam in het beantwoorden van mijn vragen. Ik had ook een extra setje buizen nodig als back-up en dat was geen probleem. Ik had een groot test panel besteld, maar de resultaten waren binnen 1 week binnen. Rapport zag er netjes uit.

ErnstVerified

“Snelle en goede service”

Je hebt de spullen snel in huis en het is duidelijk wat je daarna moet doen. Ook de uitslag heb je snel in huis, ik dezelfde avond al de eerste uitslagen. Bij een bepaling ging het fout, niet eens door het bedrijf maar door het bloedafname punt en die bepaling kreeg ik gewoon vergoed, ook het geld terug stond erg snel op mijn rekening. Vragen worden ook snel beantwoord dus al met al een positieve ervaring bij Bloedcheckup.nl

“Fijn bedrijf met geweldig veel opties…”

Fijn bedrijf met geweldig veel opties om zelfstandig je gezondheid in het oog te houden, als sporter een must want de dokters hebben toch geen verstand van wat relevant en anders is voor sport. Ook zeer tevreden over Stijn zelf! Aangename kerel en goed bereikbaar voor vragen en hulp tijdens bestellen :D

MyronVerified

My experience was very positive. I needed to pass several very specific tests. They provide 24/7 customer support. They were friendly and prompt.

Olesia TaldykinaVerified

Snelle en makkelijke afhandeling. Duidelijke instructies en binnen anderhalve dag al resultaat binnen. Top service!

ZerinaVerified

“Amazing service!”

Received a packet with everything needed, went to a walk in clinic (Amsterdam DC Clinic) where my blood was drawn and I was out the door within 5 minutes, and then after posting the samples, received results 2 days later. Results were easy to understand as well. Amazing service, would highly recommend!
