This is excellent and can only help to improve the (currently dismal) understanding of the gut biome.<p>But, it only measures bacteria and archaea.  To eukaryotes and fungi, it is blind.  And those are obviously I&#x27;m important components of gut flora.<p>Since they can be measured fairly inexpensively with more conventional means, perhaps it would improve the science if they could charge double the $99, and get a basic correlated measure of common eukaryotes and fungi in each sample.
