This whole deal is crazy, right?
I have one sister w/ full on lupus w/ hip replacement and two knees to follow - she is negative for everything, ANA-, RF-, HLAB27-. She has horrible red huge joint swelling flares complete w/ butterfly mask and vomiting.
We also have a sister who is HLAB27+ but negative everything else, who has fusing since her teens and ridiculous fibro pain, but RF- as well. She's even had elective joint fusion to relieve finger pain.
Then there's me who's positive for everything ( but low CRP & ESR ) so far, but I have awesome guts and no joint damage to speak of except some mild spinal deterioration.... I just get bouts of crazy wicked pain, eye pain, rashes, and absurd stiffness.
My point is that test results are just that. We are just who we are no matter the test results!
