Indicadores
An antinuclear antibody directed against 52 or 60 kDa RNA-binding proteins in the nucleus. They can be associated with multiple autoimmune disorders, primarily Sjogren syndrome and system lupus erythematosus. Maternal anti-Ro antibody positivity can be associated with neonatal lupus.
Pruebas
The determination of the amount of anti-Saccharomyces cerevisiae antibody present in a sample.
Indicadores
An antinuclear antibody directed against small nuclear ribonucleoproteins (snRNPs), that is highly specific, but has poor sensitivity for systemic lupus erythematosus (SLE). Presence of anti-Sm antibodies are associated with central nervous system, kidney, lung and cardiac involvement in SLE, but are not indicative of disease activity.
Glossary Term
