Frequently asked questions – Gut Health Test (Medium)

How do I interpret my results?

Results are delivered via a secure digital dashboard, where each marker is clearly explained to help you understand your findings. You can also use our AI-based chat to explore your results in more detail, ask questions, and get guidance on potential next steps, including relevant lifestyle changes or product recommendations.

Do I need to stop supplements or medication before the test?

To ensure your comprehensive stool analysis reflects your natural baseline, stop antibiotics 4 weeks before testing. Probiotics and digestive enzymes should be stopped 2 weeks prior. Always consult your doctor before pausing prescribed medications.

Is my sample stable during shipping?

Yes. The sample tubes contain a stabilizing buffer solution specifically formulated to preserve DNA and microbial integrity. This ensures your sample remains stable during shipping, even if there are transit delays or temperature fluctuations.

What is sensitivity testing?

Our stool sensitivity testing goes beyond identification. If an overgrowth is found, the lab tests it against various agents to find the most effective natural treatment for gut bacteria overgrowth, providing you with a customized roadmap for rebalancing your gut.
