Hey Tadpole-
I believe there is no blood test or other test to positivly identify Fibroyalgia, all Dr's can do is rule everything else out, which is a long process, However the "American College of Rheumatolgy Criteria", found with a random search in cyberworld, states that if pressure is put on 18 or 19 points on your body and there is pain in 11 of those points,it is said to be Fibroyalgia.[That is if everything else is ruled out]
Try looking for that website, we are not allowed to post copyrighted material or post websites, there is a lot of helpful info there.
Happy holidays, Be well +
