SSB - LA (Soluble Substance B) - IgG antibody

The SSB - LA (Soluble Substance B) - IgG antibody test is a blood test used to identify autoantibodies against the SS-B (La) antigen, a protein found inside cells. SS-B antibodies are commonly associated with Sjögren’s syndrome and are also seen in systemic lupus erythematosus (SLE) and other connective tissue diseases.

Doctors recommend the SSB - LA (Soluble Substance B) - IgG antibody test when symptoms like chronic dry eyes, dry mouth, joint pain, fatigue, or skin rashes suggest an autoimmune condition. Anti SS-B antibodies are often tested along with anti-SSA antibodies, as both can appear together in similar disorders.

The SSB - LA (Soluble Substance B) - IgG antibody test is particularly important for supporting a suspected diagnosis of Sjögren’s syndrome or lupus, differentiating between overlapping autoimmune conditions, and assessing risks in pregnant women with autoimmune diseases, as certain antibodies can affect the newborn. Early detection plays a key role in planning the right treatment and monitoring disease progression effectively.

No special preparation is required for the SSB - LA (Soluble Substance B) - IgG antibody test. Inform the doctor about all the medications and supplements currently being taken, as some of them may affect the test results. Your doctor may advise changes if needed before the test.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
