Ordering the DNA Stool Test | Comprehensive GI Effects | 3-day Collection | Europe
The DNA Stool Test | Comprehensive GI Effects | 3-day Collection is designed to give a detailed look at gut bacteria, yeast, parasites, and markers for digestion, inflammation, and immune function. This test uses advanced DNA technology to detect a wide range of gut microbes and digestive markers, helping to identify imbalances that may be linked to symptoms like bloating, constipation, diarrhea, or nutrient absorption issues. Interestingly, this test can also identify drug resistance genes in bacteria, which can help guide treatment choices if harmful bacteria are found.
Ordering this test provides several specific benefits:
- Detects both common and hard-to-find gut bacteria, yeast, and parasites using DNA analysis.
- Measures markers for gut inflammation, such as calprotectin and eosinophil protein X, to help distinguish between different digestive conditions.
- Assesses digestive enzyme levels and fat breakdown to check for problems with nutrient absorption.
- Identifies short-chain fatty acids, which are linked to colon health and may help lower cancer risk.
- Includes drug and natural agent sensitivity testing for certain bacteria, supporting more targeted treatment plans.
Who Should Consider Comprehensive Gut Microbiome and Digestive Function Testing
People who have ongoing digestive symptoms like bloating, gas, or changes in bowel habits, but have not found clear answers, may benefit from this test. For example, someone who has tried different diets and probiotics for months but still feels tired, has stomach cramps, or struggles with unpredictable digestion could use this test to find out if there are hidden imbalances or infections affecting their gut.
Ordering this test may also be helpful in these situations:
- Long-term constipation or diarrhea that does not improve with basic changes.
- Unexplained weight loss or trouble gaining weight despite eating enough.
- Food sensitivities or reactions that seem to come and go without a clear pattern.
- Fatigue or low energy that may be linked to poor nutrient absorption.
- Unexpected skin issues, such as eczema or rashes, which can sometimes be connected to gut imbalances.
This test can help pinpoint the cause of digestive symptoms by measuring specific markers for bacteria, yeast, parasites, inflammation, and digestion. Delaying this test could mean missing early signs of gut problems, which may become harder to manage if left unchecked. To get a clearer picture of your gut health and support targeted treatment, consider ordering this test now.
