Specializes in Rheumatology

No.: Positive anas can be "false" positive. On the other hand an rnp antibody is not false. This combination would indicate mixed connective tissue disease. That having been said, I have many patients with a low titer rnp positivity and no signs of disease.

A member asked:

I had ANA labs done that show a 1:80 speckled ANA, Anti SM-RNP of 3.1, RNP of 1.1. Other labs are normal. I have no family history of autoimmune disease and currently no symptoms of MCTD. Does this indicate I have MCTD or it can develop?

Feel great - incidental finding ANA 1:160 after acute sinusitis. Then had Anti-DNA, Ant-Smith, SSA/SSB, RNP, SCL-70, Centromere, and Thyroid labs all normal. Does this exclude autoimmune disorder?
