Does Microba testing test for H. Pylori?

Microbiome Explorer doesn't directly test for H. pylori, though here's how it works in practice.
​
H. pylori will only show up if it's present at over 0.01% relative abundance. If a patient has an infection but it doesn't appear, it may be because the DNA has degraded and isn't detectable in stool. And because H. pylori mostly lives in the stomach lining — and we test the microbiome of the lower large intestine — it's uncommon to detect it in stool.
​
That said, if it is there in higher abundance, our metagenomics technology will typically find it. The gold standard for detection remains the Helicobacter breath test.
