A selection of antinuclear antibodies such as ribonucleoprotein antibodies (RNP), anti-smith (anti-Sm) and anti-double-stranded deoxyribonucleic acid (dsDNA) are known to be highly specific in aiding the diagnosis of systemic lupus erythematosus (SLE). In the case of antibodies against U1 ribonucleoprotein (RNP) complex, these are vital markers for mixed connective tissue disease (MCTD).
