Pruebas
An ANA test is a blood test that looks for antinuclear antibodies in your blood. Antibodies are proteins that your immune system makes to fight foreign substances, like viruses and bacteria. But an antinuclear antibody attacks your healthy cells instead. It's called "antinuclear" because it targets the nucleus of the cells, which is in charge of sending signals that are needed for important cell functions.
Indicadores
An antiphospholipid autoantibody that reacts with beta-2-glycoprotein 1, and a member of family of autoantibodies that cause antiphospholipid antibody syndrome and may be found in system lupus erythematosus.
Pruebas
The determination of the amount of anti-DNA antibodies present in a sample.
Pruebas
The determination of the amount of anti-double stranded DNA present in a sample.
Indicadores
A type of antinuclear antibody that specifically targets double stranded DNA; while these antibodies are sometimes detectable in multiple different autoimmune disorders, their presence is generally considered highly specific for systemic lupus erythematosus.
Indicadores
An autoantibody that recognizes histidyl-tRNA synthetase, cytoplasmic protein.
Indicadores
An antinuclear antibody directed against a 47 kDa RNA-binding protein in the nucleus. They can be associated with Sjogren syndrome and system lupus erythematosus. Maternal anti-La antibody positivity can be associated with neonatal lupus.
Indicadores
An antinuclear antibody directed against U1 snRNP, that is strongly associated with mixed connective tissue disease and commonly detected in lupus.
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.
