Ordering the Comprehensive GI-Effects | DNA Stool Test | 1-Day Collection
Ordering the Comprehensive GI-Effects | DNA Stool Test | 1-Day Collection helps you find out what is happening in your digestive system by checking for bacteria, yeast, parasites, and signs of inflammation. This test uses advanced DNA technology to look at your gut bacteria and other markers, which can help you and your doctor make decisions about your digestive health.

When ordering this test, you get a detailed look at your gut health with these specific benefits:
- Checks for both good and bad gut bacteria using DNA analysis.
- Finds hidden infections like parasites, yeast, and harmful bacteria.
- Measures markers for inflammation, which can help tell the difference between IBS and IBD.
- Shows how well your body digests and absorbs nutrients.
- Identifies drug resistance genes to help guide treatment choices.
- Includes a single, easy-to-use home collection kit.
Who Should Consider Gut Microbiome and Digestive Function Testing
People who have ongoing stomach pain, bloating, or changes in their stool may benefit from this test. For example, someone who has tried different diets and probiotics but still has gas and discomfort might use this test to find out if there is an imbalance in their gut bacteria or a hidden infection.
Ordering this test may also be helpful in these situations:
- Frequent constipation or diarrhea that does not improve with simple changes.
- Food intolerances or reactions that are hard to explain.
- Unexplained tiredness or trouble focusing that may be linked to gut issues.
- Family history of digestive problems like IBD or celiac disease.
- Unexpected weight changes that could be related to how your body absorbs nutrients.
- If you suspect parasites, it is more useful to order the 3-day DNA stool tests at no additional charge.
This test gives you clear answers about your gut bacteria, infections, and how well your body digests food, which can help you and your doctor make a plan to improve your symptoms. Waiting to order this test could mean missing early signs of problems that are easier to manage when found sooner.
