Which items are measured in the IBS test?

Escheria coli
Escherichia coli (E. coli) is a type of bacteria that is naturally found in the intestines of humans and other animals. It is a gram-negative, facultative anaerobic, rod-shaped bacterium that is a member of the Enterobacteriaceae family. E. coli is a beneficial bacteria that helps to break down food and produce vitamins. However, some strains of E. coli can cause food poisoning.
Escherichia coli Biovare
Escherichia coli Biovare, a distinct subspecies of E. coli, is unusual in the human intestine. It has several forms, including hemolytic, mucoid, and lactose-negative types. Finding hemolytic or mucoid E. coli is common, especially when there's an absence of beneficial E. coli and an alkaline pH level. Elevated levels of this subspecies can indicate inadequate mucosal immunity, often due to low production of secretory IgA.
Proteus is a genus of Gram-negative bacteria known for their ability to cause urinary tract infections (UTIs), particularly in people with long-term catheters or with a compromised immune system. They are also associated with wound infections and, less commonly, with respiratory system infections. Proteus bacteria are notable for their ability to resist multiple antibiotics, making infections challenging to treat.
Klebsiella is a genus of Gram-negative bacteria found in various environments, including soil, water, and the human gut. Some species, like Klebsiella pneumoniae, are significant pathogens, causing infections in the lungs (pneumonia), bloodstream, urinary tract, and wounds. Klebsiella bacteria are known for their antibiotic resistance, which complicates treatment options and is a major concern in healthcare settings.
Pseudomonas in stool can indicate an infection or overgrowth in the gastrointestinal tract. While not a common gut pathogen, Pseudomonas aeruginosa can cause problems, particularly in immunocompromised individuals. Its presence in stool may signal an imbalance in gut flora or a more serious underlying condition, especially when accompanied by gastrointestinal symptoms.
Enterobacter, a genus of common bacteria, can be found in the human gut. Typically harmless, they form part of the natural gut flora. However, in certain conditions, their overgrowth can indicate or cause health issues. Monitoring Enterobacter levels in stool can provide valuable insights into gut health and help diagnose various conditions.
Serratia, a type of bacteria often found in the environment, can also appear in the human intestinal tract. While it's generally harmless in healthy individuals, its presence in stool might be a concern for people with certain health conditions. Detecting Serratia in stool tests can indicate potential gut flora imbalances or infections.
Hafnia, a genus of bacteria typically found in the intestinal tract, is part of the normal gut flora. While generally harmless, its presence in stool can sometimes indicate digestive disturbances or an imbalance in gut microbiota.
Enterococcus, commonly found in the human intestines and part of the normal gut flora, plays a role in gut health. However, its overgrowth in stool can indicate an imbalance or potential infection, particularly in those with weakened immune systems.
Bifidobacterium is a crucial genus of bacteria that resides predominantly in the human gastrointestinal tract. These bacteria play a vital role in maintaining gut health, aiding in digestion, and boosting the immune system. They also help in the synthesis of essential vitamins and fighting harmful bacteria. A balanced presence of Bifidobacterium is key to a healthy gut microbiome.
Bacteroides spp. are a significant group of bacteria in the human gut microbiome. They play a vital role in breaking down complex carbohydrates and producing short-chain fatty acids, which are crucial for colon health. Bacteroides are also important for immune system regulation and protecting against harmful pathogens.
Lactobacillus is a beneficial bacteria commonly found in the gut and some fermented foods. It plays a crucial role in digestive health, aiding in nutrient absorption and supporting the immune system.
Clostridium refers to a genus of bacteria, some species of which are found naturally in the human gut, while others can cause illnesses. These bacteria can survive in harsh conditions due to their ability to form spores. While certain Clostridium species play a role in gut health, others, like Clostridium difficile, can lead to severe infections, especially after antibiotic use that disrupts the normal gut flora.
Candida spp
Candida spp includes various yeast-like fungi affecting body parts like the gut and vagina. These infections often cause itching, discomfort, and discharge. They result from flora imbalance. In the gut, Candida spp can disrupt digestion. This leads to bloating and changes in bowel habits. Diet, health, and antibiotics are contributing factors. Addressing these is crucial to restore balance and relieve symptoms.
Candida albicans
Candida albicans is a type of yeast that can affect various parts of the body, most commonly manifesting as vaginal yeast infections and gut overgrowth. Vaginal infections bring itching, discomfort, and discharge, often due to flora imbalance. In the gut, overgrown Candida albicans disrupts digestion, causing bloating and bowel habit changes. Diet, health, and antibiotics influence both conditions, requiring tailored treatments to restore balance and relieve symptoms.
Yeast, a type of fungus, is commonly found in the human body, especially in the gut and on the skin. In small amounts, it's harmless. However, imbalances can lead to overgrowth, causing various health issues. Factors like diet, antibiotics, and overall health influence yeast levels.
Geotrichum candidum
Geotrichum candidum is a type of fungus often found in soil, water, air, and some food products. In the human body, it's commonly present in the gut and on the skin. While typically harmless, Geotrichum candidum can cause issues in immunocompromised individuals.
pH value
The pH value of the stool can indicate if there are any conditions of excess decay or fermentation in the intestine. A too low pH value often occurs in combination with a dysfunctional intestinal flora, as complex sugars are metabolized to fatty acids, which can contribute to an acidified stool. A too high pH value can be due to excessive amounts of protein, which can stimulate certain intestinal bacteria to produce ammonia and other metabolic products, thus raising the pH value of the stool.
Pancreatic elastase
Pancreatic elastase is an enzyme produced by the pancreas, crucial for digesting proteins. Measuring its levels in feces provides valuable information about pancreatic function. This enzyme remains stable in fecal matter, making it a reliable indicator for evaluating the exocrine function of the pancreas, particularly in diagnosing conditions like pancreatic insufficiency.
Bile acids
Bile acids, essential for digesting fats, are produced in the liver and stored in the gallbladder. Normally, they are reabsorbed into the body, but a portion ends up in stool. Analyzing bile acids in stool can help understand digestive health, especially in diagnosing malabsorption issues.
Calprotectin, a protein in white blood cells, indicates inflammation, especially in the gut. Testing calprotectin in feces shows how inflamed the intestines are. This helps diagnose and track inflammatory bowel diseases like Crohn's and ulcerative colitis. It also helps distinguish these from irritable bowel syndrome (IBS), which usually doesn't raise calprotectin levels.
Alpha-1 antitrypsin
Alpha-1 antitrypsin (AAT) is a protein primarily produced by the liver, playing a key role in protecting the lungs and other organs from enzymes that can cause inflammation. In feces, measuring alpha-1 antitrypsin can help assess intestinal protein loss and inflammation, indicating gastrointestinal disorders like inflammatory bowel disease or protein-losing enteropathy.
Secretory IgA
Secretory IgA (Immunoglobulin A) is a critical component of the immune system, primarily found in mucosal areas like the intestines, respiratory tract, and saliva. It plays a key role in the body's first line of defense, protecting mucosal surfaces by binding to pathogens and preventing their entry into the body. Secretory IgA is essential for maintaining gut health and overall immune function.
Quantitative Determination of Fat
The quantitative determination of fat in stool samples, often referred to under the umbrella of digestive residues, is a diagnostic test used to evaluate fat absorption and to identify malabsorption syndromes. This test, measures the amount of fat that is excreted in the stool. Excessive fat in the stool, a condition known as steatorrhea, can indicate problems with digestion or absorption of fat in the gastrointestinal tract. The results of this test help in diagnosing conditions such as pancreatic insufficiency, cystic fibrosis, celiac disease, and Crohn's disease.
Quantitative Determination of Nitrogen
The quantitative determination of nitrogen is a laboratory test primarily used to assess protein digestion and absorption by measuring nitrogen levels in bodily excretions, usually urine or feces. This test is instrumental in evaluating nutritional status, particularly in clinical settings where protein-energy malnutrition or imbalances might be a concern. It serves as a key indicator of metabolic functions related to protein turnover. The test can help diagnose conditions that affect protein metabolism, such as kidney disease, malabsorption syndromes, and certain metabolic disorders.
Quantitative Determination of Sugar
The quantitative determination of sugar in stool is a diagnostic test used primarily to detect carbohydrate malabsorption. This type of test is valuable for diagnosing conditions such as lactose intolerance, fructose intolerance, and other disorders where the digestion and absorption of sugars are impaired. By measuring the levels of sugars such as lactose, fructose, or sorbitol in the stool, healthcare providers can identify the specific sugars that a patient's digestive system cannot process effectively. The presence of undigested sugars in the stool often leads to symptoms such as bloating, gas, diarrhea, and abdominal pain.
Quantitative Determination of Water
The quantitative determination of water in stool, commonly referred to as stool water content analysis, is a diagnostic test used to evaluate the water content in feces. This test is crucial for diagnosing conditions associated with abnormal water absorption or secretion in the gastrointestinal tract, such as various forms of diarrhea. Diarrhea can result from infections, inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS), or malabsorption syndromes, where there is either excessive secretion or inadequate absorption of water in the intestines.

IBS Test - comprehensive digestive / gut health test

The IBS test is an in-depth test that gives you a thorough analysis of your digestive system and intestinal flora. We measure digestive function, digestive residues, bacteria and yeast in the intestinal flora, digestive malabsorption and inflammatory markers. Common imbalances in IBS are, for example, overgrowth of candida, pathogenic bacteria, lack of a healthy bacterial flora, leaky gut or digestive weakness.

Imbalance in the intestinal flora is very common in IBS and impairs the protective function of the intestinal mucosa and our immune system. Many people often say that 60-80% of individuals with IBS also suffer from SIBO (Small Intestinal Bacterial Overgrowth), a condition characterized by an excessive bacterial growth. However, experts consider SIBO a secondary disease, usually stemming from other weaknesses in the digestive system. Therefore, experts recommend conducting a thorough analysis of the gut to investigate underlying factors, which this test effectively does.. However, a SIBO test is still a complementary add-on to get an even more comprehensive overview of your gut health.

Who should take the IBS Test?

The IBS test is suitable for you who have IBS or similar stomach problems and so far have not received the right help. It suits you who either have had problems for a long time or have recently started to experience them. The sooner you find the root cause of your problems, the faster you can take action to treat the imbalances you have. If you suffer from IBS, we can recommend that you also test yourself for food intolerances and SIBO. The first step is to remove things that can disturb your gut and intestines, whether it is food you cannot tolerate, overgrowth of bacteria/fungus/yeast, or toxins.

The IBS Test analyses:

  • 13 intestinal flora bacteria
  • 4 yeast
  • The pH value
  • Digestive residues (fat, nitrogen, sugar and water)
  • Secretory IgA
  • Pancreatic elastase
  • Bile acids
  • Alpha-1 antitrypsin
  • Calprotectin

    The journey with my digestive system has been nothing short of a roller coaster. From the highs of enjoying a hearty meal to the steep drops of sudden stomach cramps, my day-to-day was unpredictable, to say the least. Multiple visits to doctors had yielded nothing concrete, apart from the usual "maybe it's stress" or "try avoiding spicy foods." With a mix of hope and skepticism, I decided to explore the IBS Test. From the get-go, the experience was more than I had hoped for. The kit, which landed on my doorstep faster than anticipated, was impressively put together. Clear, step-by-step instructions removed any apprehension I felt about taking a medical test at home. I appreciated the care and thought that went into making the process as smooth as possible for users. The real magic, however, was in the results. Detailed yet easy to understand, they painted a vivid picture of my digestive health. The confirmation of IBS was bittersweet – while no one wishes for a diagnosis, there was solace in finally having an answer. But the test went beyond just a label. It delved deep into triggers, patterns, and even provided guidance on potential next steps. Empowered with this newfound knowledge, I sought professional dietary advice. A few tweaks here, a couple of substitutions there, and within weeks I started to notice a difference. The frequency of my flare-ups reduced, the severity of cramps lessened, and I began to feel more in control of my body. In retrospect, the IBS Test was a turning point. It transformed a nebulous cloud of symptoms into tangible data that I could act upon. For anyone wading through the murkiness of digestive discomfort without clear answers, I wholeheartedly recommend taking this plunge. It's truly illuminating.
