Sjögren's Syndrome B (SS-B/La) Antibody details
What Sjögren's Syndrome B (SS-B/La) Antibody shows
SS-B (La) antibodies are autoantibodies associated with Sjögren's syndrome and lupus, often found together with SS-A antibodies, though less commonly present on their own. Like SS-A, they carry some relevance during pregnancy due to a small risk of affecting the developing baby's heart rhythm, so their presence — particularly alongside SS-A — is sometimes taken into account for pregnancy monitoring in women with these antibodies.
Tests that include Sjögren's Syndrome B (SS-B/La) Antibody
SS-B (La) Antibodies are autoantibodies directed against the La protein, commonly associated with autoimmune conditions. Elevated levels are often found in Sjögren’s syndrome and systemic lupus erythematosus (SLE) and help support the diagnosis of these diseases.
- Sjögren's Syndrome B (SS-B/La) Antibody An autoantibody associated with Sjögren's syndrome and lupus, often found alongside SS-A antibodies.

- Sjögren's Syndrome B (SS-B/La) Antibody An autoantibody associated with Sjögren's syndrome and lupus, often found alongside SS-A antibodies.
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.
