Hi there Liz,
interesting reading about EpicGenetics’ Fm/a blood test.
Like AussieMom I’d never heard of it either, but have had a look at a lot of pages, and it’s been spoken about here too, 2019 and 2017. The company just concentrates their check on 4 proteins (cytokines & chemokines) they think are reduced in fibro. It’s not acknowledged tho, because it contradicts most research. The price has gone up from 800$ 2013 to 1200$ nowadays, some insurances pay for it…
Here is a really brilliant, all-encompassing, balanced, but also very complicated article from Dec19 with loads of high-level informative comments (background on Gillis and EpicGenetics) up to the present:
Shorter and easier:
“Countingmyspoons”
says she only saw sense in doing it, because of a fibro-vaccine EpicGenetic are trying to develop (see the first link):What EpicGenetics on fmtest.com say themselves about fibromites who’d be best for the test I probably wouldn’t score highly… 
But I don’t care, I don’t need anyone to tell me what I have any more. 
- I just dare someone to get closer to what helps me than I am myself… 
And I’m definitely not taking a vaccine.
I wonder how it can be possible to develop and propogate an indicator test such as this as reliable - how can you verify it, if there isn’t anything safe you can base it on, like say 1000 people who definitely have fibromyalgia? I’d say you can’t, because you just can’t definitely diagnose fibromyalgia and it is also a fuzzy condition, I think probably an overlay and a collection of shared symptoms of various/combined origins. Once these have been differentiated things will get a bit easier, probably in the process.
