Hi John, that’s what my nephrologist told me. I had kidney problems; bleeding, right renal artery stenosis et al so He would always check bloodwork etc. Rh level was in the 500’s. I should my rheumatologist and his response was that everyone has elevated. rh levels. So, went back to nephrology (whom I have the highest regards for) adamantly disagreed. He said RA. Switched rheumatologist and she said I d have RA. But now, he said my blood work is baffling him. In his opinion I’m transitioning to mixed connective …I’m determined that no matter what “it” is, I want my bucket list to be longer than my medical list.
