Hello Carol, and welcome to our very supportive forum! Good idea to reach out in this situation.
Oh dear, how perturbing your situation would seem to be! So long on the FM-track, and a result which maybe was meant to dispel doubts rather than confirm them, which is now de-tract-ing you.
But: You have been diagnosed and you yourself are sure your symptoms have always been the classic ones.
So safe that sounds that I'm wondering why you felt you needed this test at all.
And landing on Alan's thread means you probably know that the Fm/a test itself is not ... necessarily.... a scandal, like the title suggests, it's more the fact that Gillis pretended to keep up his idea of a BCG vaccine being tested as a cure, to reinforce the legitimacy of his test. That might be why you haven't just bitterly retorted that the negative result is obviously wrong, like Gillis.
Well... Your Fm/a-test has
only measured that the amount of cytokines and chemokines in your blood are different to the levels
Gillis expects for FM. Meaning you might still have a different subtype of FM, so still have FM, like you and the rheumatologist have thought all along. Also: All fibro-researchers see cytokines etc. at most as a possible biomarker, their levels don't even necessarily support the autoimmune hypothesis, aside from the other big hypotheses (Central Sensitization, Mast Cells & ATP).
Remember Gillis is not a researcher, he is an "entrepreneur". I'm still not even happy with the snake oil name "EpicGenetics"....
So you have many reasons to consider the test as
wrong. Wrong for you, or even wrong for fibro generally.
And even if you can't "let go" (yet?) - your mode of action can be the same. If you as you say have the classic symptoms of fibro, whether or not you can see yourself as truly fibromite or not: You are very welcome with all that here, to read & follow
@sunkacola's advice-post and all the other good ideas here on the forum, ask detailed questions, moan & vent, whatever. ("You aren't an imposter, don't let Gillis make you believe that").
So you could say nothing (much?) has changed, you're still on track!
