So I have heard two things. 1: You can only test positive for Lupus if your in a flare, and 2: if you have Lupus you will always test positive. Which is it? And is MS the same way? If my MRI comes up clean, can it still be MS? And, finally if its my thyroid, and the basic test is normal, what specific testing can I ask for, for that? Seems like I have to hold my doctors hands and guide them thru everything. Thanks Team. I have so much hope for the future, and a week ago I was ready to just give up. You have all made this so much more bearable.
