Een ontstekingsremmend eiwit dat vrijkomt wanneer bepaalde witte bloedcellen (neutrofiele granulocyten) sterven. Het bindt calcium en zink. Bovendien deactiveert het de microbiële enzymen waardoor de antibacteriële werking tegen schadelijke micro-organismen wordt onderdrukt. Bij chronische darmontstekingsziekten (IBD), zoals de ziekte van Crohn en colitis ulcerosa, hopen zich grote hoeveelheden witte bloedcellen op in de darmwand. De gemeten hoeveelheid calprotectine in de ontlasting komt overeen met het aantal ontstekingscellen in het maagdarmkanaal en kan dus gebruikt worden als maat voor de ernst van de ontsteking.

Strong scientific evidence

This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.

Rationale for this test

Fecaal calprotectine is een gevestigde ontstekingsmarker voor inflammatoire darmziekten (IBD) zoals de ziekte van Crohn en colitis ulcerosa. De test wordt in Nederlandse zorgrichtlijnen gebruikt om de ernst van darmontsteking te monitoren en de effectiviteit van behandeling te beoordelen. De klinische betekenis is goed onderbouwd binnen de reguliere geneeskunde.

Frequently asked questions

Answers to what people usually want to know.

View instructionsFull instructions with visual guidance
How does the stool test work from A to Z?

After ordering we ship the kit to your home. You collect a small sample with the included scoop, keep it cool and return it in the envelope. You receive the result digitally by email.

How do I collect a clean sample?

Lay plastic film over the toilet or use a clean container. Scoop from the middle of the stool and avoid contact with urine or toilet water.

How much stool do I need?

A small scoop with the included spoon is enough — about half a teaspoon. More is not better.

How long can I keep the sample before shipping?

Maximum 24 to 48 hours in the fridge. Send as soon as possible and preferably early in the week, not just before the weekend.

Should I avoid medication or food before collection?

Some analyses (like calprotectin) ask you to avoid NSAIDs or certain supplements 24-48 hours before collection. Check the instructions with your kit for the exact preparation for your test.

When and how do I receive my result?

Stool analyses typically take about a week 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!!

Madina ShinwariVerified

“Bloedcheckup levert”

Waar ziekenhuizen moeilijk doen om checkup te doen , komt Bloedcheckup naar boven drijven als vertrouwde partner op gebied van gezondheid. Ik ben uiterst tevreden met bloed checkup

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”

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

“Top!”

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!
