Ordering the Comprehensive Stool Analysis | Canada
The Comprehensive Stool Analysis helps identify digestive problems, bacterial imbalances, and food intolerances by measuring specific markers in your stool. This test can detect issues like yeast overgrowth, parasites, and inflammation, which may not show up in other types of testing. Interestingly, this test can also reveal hidden immune reactions in the gut that may be linked to symptoms outside the digestive system, such as fatigue or skin problems.
Ordering this test can help you:
- Pinpoint the cause of ongoing bloating, gas, or abdominal pain
- Detect hidden infections like parasites, yeast, or harmful bacteria
- Identify food intolerances to gluten, dairy, soy, or eggs
- Measure gut inflammation and immune response markers
- Check for digestive enzyme problems that affect nutrient absorption
Who Should Consider Digestive and Microbiome Testing
People who have frequent stomach pain, loose stools, or trouble digesting certain foods may benefit from this test. For example, someone who has tried many diets but still feels tired, bloated, or has unpredictable bowel movements could use this test to find out if a hidden gut problem is causing their symptoms.
Ordering this test may also be helpful if you:
- Have unexplained diarrhea or constipation that does not improve with simple changes
- Notice mucus or blood in your stool
- Experience frequent nausea or loss of appetite
- Have a family history of digestive conditions like IBS or IBD
- Recently traveled and developed new stomach symptoms, even if mild
Testing can help you find the exact reason for your symptoms, such as a specific infection, food intolerance, or enzyme problem, so you can take steps to address it. Delaying this test may allow gut issues to continue, which can make symptoms harder to manage over time.

Labs Included When Ordering Your Comprehensive Stool Analysis
| Test Name | Reference Range | What This Test Measures | Low and High Levels of Comprehensive Stool Analysis |
|---|---|---|---|
| Digestive Function Markers | |||
| Chymotrypsin | >8.0 U/g | Chymotrypsin is a digestive enzyme that helps break down proteins in your food. It shows how well your pancreas is working to support digestion. |
High levels mean your pancreas is releasing more enzyme, which can happen with fast digestion.
Low levels mean your pancreas may not be making enough enzyme, leading to poor protein breakdown. |
| Fecal pH | 6.0–7.5 | Fecal pH measures how acidic or alkaline your stool is, which can reflect your gut bacteria balance and digestion of carbohydrates. |
High levels mean your stool is more alkaline, which may suggest less healthy bacteria or slow digestion.
Low levels mean your stool is more acidic, often linked to too much fermentation or certain infections. |
| Occult Blood | Negative | This test checks for hidden blood in your stool, which can be a sign of irritation, inflammation, or injury in your digestive tract. |
High levels mean blood is present, which may point to inflammation, ulcers, or other gut problems.
Low levels mean no blood is found, which is normal. |
| Alpha Anti-Chymotrypsin | <40 mg/dL | Alpha anti-chymotrypsin is a protein that rises with gut inflammation. It helps show if your digestive tract is irritated or inflamed. |
High levels mean there may be inflammation in your gut.
Low levels mean little or no inflammation is present. |
| Intestinal Lysozyme | <600 ng/mL | Lysozyme is an enzyme made by immune cells in your gut. It increases when your body is fighting bacteria or inflammation in the intestines. |
High levels mean your gut is reacting to bacteria or inflammation.
Low levels mean there is little immune response in your gut. |
| Total Intestinal SIgA | 510–2040 µg/g | SIgA is an antibody that protects your gut lining. It shows how your immune system is working in your digestive tract. |
High levels mean your immune system is very active in your gut, often due to infection or irritation.
Low levels mean your gut immune defense may be weak. |
