SS-A (Ro) near me in Patna

SS (Sjogren Syndrome) -A (Ro) is a blood test used for the evaluation of patients with signs and symptoms of Sjogren Syndrome (an autoimmune disease characterized by dry mouth and dry eyes). SS-A (Ro) is commonly referred to as extractable nuclear antigen (ENA). Antibodies to ENA are found in 60- 90% of the patients with Sjogren Syndrome, 40-60% of the cases of systemic lupus erythematosus, and in rheumatoid arthritis patients.

ELISA (Enzyme-Linked Immunosorbent Assay) method is used to measure the IgG antibodies. The reference values are <1.0 U for a negative test and ≥1.0 U for a positive test. The positive test indicates connective tissue diseases. A positive result in pregnant women with LE indicates an increased risk for congenital heart block in neonates.
