Sample Collection: What impact does Loperamide (Gastro Stop) have on Microbiome Explorer test results?

There is no evidence that Loperamide interferes analytically with immunoassays or occult blood tests
However:
Loperamide may alter the gut microbiome and indirectly affect test interpretation.
- It can influence stool consistency and timing, which may affect results for zonulin or elastase.
- Loperamide use has been linked to increased bacterial richness and changes in relative species abundance.
- For chronic or high-dose use, note it on the request form to aid interpretation.
