I have just added this to the site for comparing results from different tests. http://microbiomeprescription.azurewebsites.net/
Below are some of mine. Remember the first one in 2019 was onset of ME/CFS and it has since moved much closer to recovery (but not all of the way there). uBiome does provide a Diversity number, but it is a black box. I opted to count the number at each taxonomic level instead and then show as a percentile compared to other uploaded samples.
It was interesting that ME/CFS signature shows up at the species level best. A ton of new species appeared with onset.
