A Spanish Microbiome Test and Analysis

A reader in Spain forward the results they received from Estudios Analiticos Aplicados a la Clinica, Madrid, Spain. I have done two other reviews using sample reports recently (A US Microbiome Test: GI-MAP and Another German Microbiome Test Review), It is nice to do one  with actual patient data.


Criteria: Look at the current list of deep dives of 69 bacteria genus(which comes from high values seen in uBiomes from CFS readers) and count the number of matches, just like I did in posts above. We get 8 or 12% covered by this test (discussion at bottom).

This Report Result

First — I like this report visually and it’s content

  • There are ranges based on Spanish population
    • Less variation due to genetics
    • Less variation due to differences in diets
  • There are RANGES, if you look at the first chart below we see some ranges are huge and some ranges are small.
    • Because uBiome lacks ranges, I have arbitrary picked 1.5x as a threshold. Looking at Bacteroides below we see the normal range is 8-10. A 11 would be an abnormal high. Using my rule of thumb we have 9 x 1.5 = 13.5 as the threshold for abnormal high so a value of 12 would be deemed normal for me but abnormal using ranges (the correct answer).








Bottom Line

A nice summary is provided at the bottom of abnormalities. Some abnormalities are not cited because they are clinically significant by traditional standards:

  • E.Coli is low normal:  5.4 on a range of 5-7.5
  • Bifidobacterium is low: 6.0 on a range of 6.5-8.5
  • Lactobacillus is low normal: 5 on a range of 4.5-7
  • Firmicutes is low: 8 on a a range of 8.5 -11
  • Akkermania is normal: 7.3 on a range of 5-8
  • Bacteroidetes is low: 7.04 on a range of 8 – 11
    • Note: the Firmicutes:Bacteroidetes normal ratio on this test would be 1.02 to 1 NOT 2.1:1 reported on uBiome — we may have differences of lab process being involved 😦
    • The ratio here is 1.09, high (ALTO)
  • We have significantly low pH (5.5 vs normal range of 6.0- 7.2) – thus excessive acid.

All of the items below are for low (BAJO) bacteria genus – not overgrowths (ALTO)!


The short coming

The report is centered at the Phylum (50’000 meter view) level with a few specific genus being checked (i.e. Enterobacteriaceae, Pseudomona, Campylobacter, Heliobacter, Akkermansia, Saccharomyces, Bacteroides, Prevotella, Clostridium, Staphylococcus, Enterococos, Roseburia, Eubacterium, Faecalibacterium). Of these, 8 or 12% are on the list of bacteria genus seen with CFS. This means that there is about a 50% chance of seeing any highs bacteria genus (assuming 8 genus are high in a CFS patient’s ubiome).

In other words, you may have major overgrowth causing the low bacteria genus detected by this test but not a single high bacteria genus reports!

Personal View

The test presentation and information is a big positive. The very limited coverage of bacteria genus is a negative — but it is a lot better than the two prior tests that I reviewed.

I would say that taking this test PLUS uBiome would be a good combination. If you happen to be high in one of the 8 covered bacteria genus — then having the local population based ranges is superior to my rule of thumb of 1.5x.

Advise to the reader – this is tough because I can only give advice to alter the Firmicutes:Bacteroidetes ratio, see this post


  • capsaicin [2016] Chili Peppers
  • Dairy products [2016]
  • Proton pump inhibitor [2016]


  • Resveratrol [2014]
  • Lactobacillus Fermentum [2017]
  • Pea Fibre [2017]
  • Melatonin [2017]
  • Cranberry [2017]

… and get a uBiome done.
