Know more about this test

The Anti SS-B ( Sjögren Syndrome-B) antibody test is one of the most important tests used in evaluating patients with connective tissue disease. This serological test is especially recommended in those patients with a positive antinuclear antibody test and those with symptoms of lupus and Sjögren syndrome. The test helps in early detection of any autoimmune disease in the body and doctors can decide the early course of treatment.

Please note: This is an outsourced test. The sample for this test is collected by TATA 1MG and processed at a NABL accredited partnered lab.

What does Anti SS-B Antibody measure?

The Anti SS-B Antibody also known as the Anti-La antibody test, detects antibodies against the SS-B (La) antigen, which is often associated with autoimmune diseases like systemic lupus erythematosus (SLE), Sjögren's syndrome, and other connective tissue disorders. A positive result can suggest an increased risk for these conditions, particularly Sjögren’s syndrome, and may also be linked to complications such as neonatal lupus and congenital heart block in infants born to mothers with anti-SS-B antibodies. While a negative result generally indicates these conditions are less likely, it does not completely rule them out, as some individuals with these autoimmune diseases may not test positive for Anti SS-B antibodies.
