my daughter had severe joint pain. I took her to pediatrician and had bloods drawn. ALL of her inflammation factors were abnormal. Meh, we went to the pediatric rheumy and dealt with the issue.
Yep my daughter's platelets, sed rate, ana, CRP, and another one were wonky. ANAs can often be + and it mean nothing. I remember the pediatric rheumy saying to me, " You don't think anything is wrong do you? But I will tell you, in my 25yrs of practice I have NEVER seen blood work like this and it be nothing" I said "Well I know it isn't ___ cuz my mom had that. Maybe
it is _____." Well it was the maybe I thought. We dealt with it and have gone on.
IF you have something, you will deal and go on. You don't really have a choice
. However, as your doc mentioned ANAs and +RNP can often give false +. This likely the case in as much as your inflammation tests were normal.
Several years ago I had an anti-phospholipid come back positive. The next time it was done, it came back negative. Lots of these immune disorder tests do that. My understanding is when those type test come back + but other inflammation type stuff is normal, it is most likely false positive. Typically, too, no dx is ever made based on ONE + auto-immune test. I suppose it is because docs know the tests record. I have a friend who has a MIXED auto-immune disorder, one of the mix was hashi-moto. She was sick lady. Docs knew something was wrong. she had one ana come back + but docs weren't jumping on auto-immune disease/s based on that one test.. She took 3 or so and then docs looked at other abnormal stuff going on.
BTW--- QUIT googling stuff up. It ONLY HARMS YOUR WELL BEING
