This test measures

  • EPX (eosinofiele proteïne x)
One of the four major proteins found in the granules of human eosinophilic leukocytes (granulocytes). They play a key role in the allergic inflammatory process. EPX is used as a parameter in feces to detect inflammation and atopic eczema caused by allergies and/or food intolerances, to measure the degree of activity of the present inflammation, and to test the effectiveness of an elimination diet. Experience shows that EPX also responds to parasitic infections.

Limited evidence in mainstream medicine

The scientific support for this test within mainstream Dutch healthcare is limited. The test is not included in NHG/FMS standard guidelines.

Rationale for this test

EPX in feces wordt in de productbeschrijving gepresenteerd als marker voor allergische ontstekingen en voedingsintoleranties. Deze toepassing is niet opgenomen in Nederlandse zorgrichtlijnen voor voedselallergie-diagnostiek. De reguliere diagnostiek bij vermoeden van voedselallergie bestaat uit anamnese, huid-prik-test, specifiek IgE en eventueel voedselprovocatie. De wetenschappelijke onderbouwing voor EPX-bepaling in feces binnen de Nederlandse reguliere zorg is beperkt.

Practical information

Frequently asked questions

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 receive your laboratory report securely by email. It lists the measured values, units, reference ranges and any flags added by the laboratory.

How do I return the collection materials to the lab?

Use the supplied return envelope and place it in the letter-mail bag inside a PostNL service point yourself as soon as possible. Do not hand it to counter staff or request track & trace. The instructions supplied with your test state when it must be sent.

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.

“I am satisfied with the service”

I received a referral by email, just like from a GP. I did not have to send anything by post and could quickly visit a local blood collection centre. The results were fast and clear. The price was good, not too expensive, and all messages were secure.

kraljicaVerified

“A very good experience”

A very good experience! I received quick answers to my questions, a custom blood test was put together, everything was arranged smoothly, and I could have my blood drawn by a healthcare professional nearby. The results were available within a few days. In short, very satisfied!

PhilVerified

“Very good customer service”

The customer service is very good. I had a complex request, which caused an issue at the blood collection centre. Customer service resolved it very well. They also offer a wide range of tests at a reasonable price.

Marc EekhoutVerified

kambalesVerified

“Very happy to have found this business”

Very happy to have found this business. We need to check our blood more often :) The process was easy. They sent me the kit at home, then I had to go to a clinic with the papers and they knew what they had to do. I got the results in less than a week.

DenisaVerified

“Smooth process and good support”

Amazing website experience. I ordered various tests for 2 people. We went to one of the supported centers and took samples. Also after the results were ready, I needed a letter from the laboratory and they prepared the letter for me in no time. Definitely recommended.

Majid HajiheidariVerified

“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!

Trudi CoetzeeVerified

“Great customer service”

I ordered a test through bloedcheckup.nl but later realized I no longer needed it. I contacted their support team, and they were very quick, responsive, and helpful in handling my cancellation. The whole process was smooth and efficient. Great customer service!
