Does Microba kits test for SIBO?

No — Microbia doesn't test for SIBO, and we know that can be frustrating because SIBO is difficult to diagnose.
​
Here's why. SIBO means there are excessive — often gas-producing — colonic microbes in the small intestine. Microbiome Explorer looks at microbes in the distal colon, and we can't assume the microbes there are also present in the small intestine. The two environments are different.
​
If SIBO is suspected, patients should be referred for further testing. It's worth noting that there's currently no validated gold standard for SIBO testing across the field.
