I recently went to the doctor with severe headache, rash, joint pain, low grade fever, and fatigue. When the bloodwork came back my ANA was 1:640. I know it's possible for it to be a false positive for Lupus since it is just a screener, but I am curious if it is likely at a titer that high. The doctor has since ordered more bloodwork but it will be three weeks until it all comes back and I am anxious. Does anyone have any thoughts on this? I am a 29 year old female. Thank you so much in advance!
