The human organism responds with an inflammatory reaction to attacks by invading pathogens (microorganisms and viruses) or in case of damaged tissue (after accidents or surgery).
In this qualitative inflammation screening, the presence of the inflammatory-mediated parameters calprotectin, lactoferrin, hemoglobin and transferrin is determined (negative = 0 / positive = 1). In case of a positive value for one of these parameters in the stool, we advise to also quantify the respective parameter(s).
In addition, the parameter PMN-elastase is determined. The value of PMN elastase is regularly elevated, even when the aforementioned inflammatory markers are not present.
The parameters calprotectin and lactoferrin are useful in differentiating between functional (e.g. irritable bowel syndrome) and organic diseases (e.g. chronic inflammatory bowel diseases). Gastrointestinal inflammatory diseases also include Crohn's disease and ulcerative colitis. A strong suspicion of these may exist in patients who have persistent (≥ 4 weeks) or recurrent (≥ 2 episodes per six months) abdominal pain or diarrhea. The presence of rectal bleeding, weight loss, or anemia increases the probability of the diseases. Endoscopic examination with histopathological tissue sampling is often indispensable for diagnosis.
Note: Patients should not collect stool samples for this test if they are menstruating, have bleeding hemorrhoids or blood in their urine, or if they have strained during defecation!
This test has clinical value for specific complaints or indications, but is not intended as screening without symptoms.
Rationale for this test
Deze fecale ontstekingsscreening combineert meerdere markers (calprotectine, lactoferrine, hemoglobine, transferrine, PMN-elastase) om onderscheid te maken tussen functionele darmklachten en organische darmontstekingen zoals de ziekte van Crohn of colitis ulcerosa. Calprotectine en lactoferrine zijn gevalideerde markers binnen de Nederlandse zorgrichtlijnen voor deze differentiatie. De kwalitatieve screening is echter minder geschikt als stand-alone diagnosticum; bij positieve uitslag is kwantitatieve bepaling en klinische context noodzakelijk voor verdere diagnostiek.

View instructionsFull instructions with visual guidanceAfter 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.
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.
A small scoop with the included spoon is enough — about half a teaspoon. More is not better.
Maximum 24 to 48 hours in the fridge. Send as soon as possible and preferably early in the week, not just before the weekend.
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.
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.
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.
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.

“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.
“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

“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!
