Clinical Information. Antibodies to RNP occur in approximately 50% of patients with lupus erythematosus (LE) and in patients with other connective tissue diseases, notably mixed connective tissue disease (MCTD). MCTD is characterized by high levels of RNP antibodies without detectable Sm or double-stranded DNA (dsDNA) antibodies.

What is normal range for RNP antibodies?

specific ANA-related antibodies to test high was RNP (>8 when the normal range is 0.0-0.9).

What does high RNP antibodies mean?
