The Anti LA (Anti-SSB) test detects the presence of Anti-SSB antibodies in the blood, which are often associated with autoimmune disorders such as Sjögren's syndrome and systemic lupus erythematosus (SLE). This test is crucial for diagnosing these conditions and monitoring disease activity. A 1 ml serum specimen is required for this test, which provides results in 7 days. Priced at 1100 THB, it helps in understanding the presence of autoimmune activity in the body.
