Sjögren's Syndrome A (SS-A/Ro) Antibody details
What Sjögren's Syndrome A (SS-A/Ro) Antibody shows
SS-A (Ro) antibodies are autoantibodies associated most strongly with Sjögren's syndrome (an autoimmune condition causing dry eyes and dry mouth) and also seen in lupus. They carry particular clinical relevance during pregnancy: if present in a pregnant woman, these antibodies can cross the placenta and, in rare cases, cause a heart rhythm problem in the developing baby (congenital heart block) or a temporary skin rash in the newborn, so pregnancies in SS-A-positive women are sometimes monitored more closely with specialized fetal heart rhythm screening.
Tests that include Sjögren's Syndrome A (SS-A/Ro) Antibody
SS-A (Ro) Antibodies are autoantibodies linked to autoimmune diseases, particularly Sjögren’s syndrome and systemic lupus erythematosus (SLE). Their presence can also be associated with neonatal lupus and congenital heart block when found in pregnant individuals.
- Sjögren's Syndrome A (SS-A/Ro) Antibody An autoantibody associated with Sjögren's syndrome and lupus; also relevant in pregnancy due to a risk of neonatal heart complications.

- Sjögren's Syndrome A (SS-A/Ro) Antibody An autoantibody associated with Sjögren's syndrome and lupus; also relevant in pregnancy due to a risk of neonatal heart complications.
ANA + 11 Components is a comprehensive blood test that includes the presence of antinuclear antibodies (ANAs), which are autoantibodies targeting the cell nucleus. A positive ANA screen suggests potential autoimmune activity. 11 ANA Components tests for 11 specific autoantibodies against distinct nuclear antigens, helping to identify or differentiate particular autoimmune diseases.
- Chromatin Antibodies Autoantibodies that target chromatin (DNA-protein complexes) inside your cells. Associated with lupus and other autoimmune conditions.
- Anti-Jo-1 An autoantibody associated with certain autoimmune muscle and lung conditions, including polymyositis, dermatomyositis, and antisynthetase syndrome.
- Ribosomal P Antibody An autoantibody associated with lupus, particularly linked to neuropsychiatric symptoms in some patients.
- RNP Antibody An autoantibody associated with mixed connective tissue disease and, at times, lupus.
- Smith (Sm) Antibody An autoantibody highly specific for lupus, though present in only a portion of people with the disease.
- Centromere B Antibody Autoantibodies that target a structure inside your cells called the centromere. Strongly associated with limited scleroderma (CREST syndrome).
- Double-Stranded DNA (dsDNA) Antibody Antibodies against double-stranded DNA. Highly specific for lupus and often used to track disease activity.
- Scleroderma (Scl-70) Antibody An autoantibody strongly associated with diffuse systemic sclerosis (scleroderma), a more widespread form of the disease.
- Sjögren's Syndrome A (SS-A/Ro) Antibody An autoantibody associated with Sjögren's syndrome and lupus; also relevant in pregnancy due to a risk of neonatal heart complications.
- Sjögren's Syndrome B (SS-B/La) Antibody An autoantibody associated with Sjögren's syndrome and lupus, often found alongside SS-A antibodies.
- Sm/RNP Antibody Measures antibodies to the Sm/RNP complex, autoantibodies linked to mixed connective tissue disease and lupus, used when evaluating a positive ANA.
Sjögren's Antibodies (SS-A, SS-B) - Sjögren's antibodies (SS-B) is detected in approximately 15% of patients with Sjögren's Syndrome. Sjögren's antibody (SS-B) is present only if Sjögren's antibody (SS-A) is also detected. The presence of both antibodies (SS-A and SS-B) strengthen the diagnosis of Sjögren's Syndrome and conveys prognostic information.
- Sjögren's Syndrome A (SS-A/Ro) Antibody An autoantibody associated with Sjögren's syndrome and lupus; also relevant in pregnancy due to a risk of neonatal heart complications.
- Sjögren's Syndrome B (SS-B/La) Antibody An autoantibody associated with Sjögren's syndrome and lupus, often found alongside SS-A antibodies.
