I don't believe they have communicated with each other, the GP said this isn't my area and sent me back to my gastro who is treating the PBC, who then said the liver is his specialty so I should go to a rheumatologist. He redid the blood work to verify that the RNP number was right on the first blood test, and ordered other tests. He said my blood work looks good except for the 6.7 RNP number. I also had elevated uric acid. So he verified the RNP is indeed elevated, and then said I don't know why, lets wait 4 months and retest. He did order another blood test for muscle enzymes. We should have results next week. I'm not sure what that will show.
