Doctor's answer (2)
Dr. Kou Linlin
Hello, the antinuclear antibody (ANA) panel is primarily used to screen for autoimmune disorders, such as systemic lupus erythematosus (SLE), Sjögren’s syndrome, scleroderma, dermatomyositis, rheumatoid arthritis, and systemic sclerosis. Among these, anti-Sm antibodies and anti-double-stranded DNA (anti-dsDNA) antibodies serve as diagnostic markers for systemic lupus erythematosus. We hope this information is helpful to you. Wishing you a happy and healthy life!
