The human colon contains 10¹¹ bacteria per gram, making it home to the largest bacterial population in the body. Most of these are anaerobic.
The intestinal microbiota consists of a resident and a transient intestinal microbiota. These consist of aerobic, anaerobic, and micro-aerophilic intestinal bacteria.
The resident intestinal microbiota consists of intestinal bacteria that are absolutely necessary for the physiological processes in the intestines. Its exact composition develops in the first years of life and is as personal as a fingerprint.
The resident intestinal microbiota consists of the following bacteria:
Of the anaerobic bacteria, 25% consist of Bacteroides species. These have a beneficial effect on their host in the intestine. Numerically, they form the largest group of bacteria and are therefore an important part of colonization resistance. This means that pathogens do not get a chance to attach to the intestinal wall, because it is protected by resident bacteria, including Bacteroides species.
In particular, indigestible carbohydrates are converted by them into short-chain fatty acids and hydrogen. This makes this group of bacteria important in supporting Bifidobacteria. A good Bifidus intestinal microbiota is particularly dependent on a good Bacteroides intestinal microbiota. To support both groups of bacteria, there are no probiotics, but there are prebiotics, such as inulin.
Outside the intestine, however, Bacteroides species are important clinical pathogens. They are found in most anaerobic infections, with or without abscess formation. The Bacteroides species contain the most antibiotic-resistant mechanisms of all anaerobic bacteria. They can adapt very well to new circumstances:
Some antibiotics to which Bacteroides are resistant include cefotaxime, clindamycin, metronidazole, carbapenems, and fluoroquinolones (e.g., gatifloxacin, levofloxacin, and moxifloxacin). Bifidobacterium species, like Bacteroides species, form a large part of the resident intestinal microbiota. They convert carbohydrates into short-chain fatty acids such as acetic acid, formic acid, succinate, and ethanol. This achieves a lower acidity of the intestinal environment, which counteracts putrefaction processes. Through the production of short-chain fatty acids, they work synergistically with Lactobacilli and Enterococci. Furthermore, they can split bile acids and inhibit the multiplication of transient bacteria. However, the amount of Bifidobacterium species decreases after the age of 50, which can lead to putrefaction processes and the intestinal microbiota becoming more susceptible to dysbiosis.
Escherichia coli contributes to colonization resistance by producing antimicrobial substances. Furthermore, this bacterium stimulates the immune system of the intestines and contributes to the stabilization of the intestinal barrier. Therapeutically, this bacterium is used to improve mucosal immunity (sIgA, beta-defensin 2). It also removes oxygen from the food bolus and from the intestinal wall to ensure a stable anaerobic environment in the intestine, allowing for a balanced anaerobic intestinal microbiota with Bifidobacterium and Bacteroides species.
Enterococcus species can convert carbohydrates into short-chain fatty acids that acidify the intestinal environment and inhibit the growth of transient bacteria. To support colonization resistance, they produce important bacteriostatic and bactericidal substances. They can also convert proteins. They are used therapeutically to improve mucosal immunity. They also remove oxygen from the food bolus and from the intestinal wall to maintain an anaerobic intestinal environment.
Lactobacillus species grow under oxygen-poor conditions. They are saccharolytic bacteria; they only convert carbohydrates. Their metabolic products prevent the growth of foreign germs such as Clostridium and Proteus species. This type of proteolytic intestinal microbiota (protein-loving species) is inhibited by the acidification of the intestinal environment and the production of bacteriocin.
The transient intestinal microbiota consists of:
An important part of mapping the aerobic transient intestinal microbiota is the investigation of Enterobacteria. Here, the qualitative determination of the various species of Enterobacteriaceae is central. Within the Enterobacteriaceae species, there are a number of species that have various pathogenic properties. Some obligate pathogenic species from this family are Salmonella, Shigella, and Yersinia species. Urease-producing species like Proteus species can increase serum ammonium concentrations in patients with impaired liver function. Various species of Enterobacteriaceae are involved in rheumatoid reactions, including Enterobacter and Klebsiella species.
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
Deze test meet de samenstelling van darmbacteriën in ontlasting. Hoewel het microbioom een actief onderzoeksgebied is, bestaat er binnen de Nederlandse reguliere zorg geen gevestigde klinische toepassing voor deze test bij gezonde personen zonder specifieke indicatie. De test is niet opgenomen in NHG- of FMS-richtlijnen voor diagnostiek van darmklachten.

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.

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