WebTest Details Use Anti-U1 RNP antibodies typically appear in both SLE and MCTD. In MCTD, the presence of U1 RNP is required for diagnosis, whereas anti-RNP antibodies occur in only 30-40% of SLE. MCTD is typified by the high-titer RNP antibody activity in isolation; anti-RNP antibody activity in SLE commonly accompanies anti-Sm antibodies. WebAntibodies to U1 RNP are present, usually at very high titers. Antibodies to the ribonuclease-resistant Sm component of extractable nuclear antigen (anti-Sm antibodies) and to double-stranded DNA (negative in MCTD by definition) are measured to exclude other disorders.
