Anti-SS-A (Anti-Ro Antibodies)

This test detects antibodies linked to several autoimmune conditions, most notably Sjögren’s syndrome and systemic lupus erythematosus (SLE).

• Diagnostic Use: Anti-SS-A is a key marker for diagnosing Sjögren’s syndrome, especially in patients with dry eyes, dry mouth, or salivary gland issues.
• Broader Associations: It can also be present in lupus, where it may be linked to skin manifestations such as photosensitivity or subacute cutaneous lupus.
• Pregnancy Considerations: In expectant mothers, Anti-SS-A is important to identify because it can be associated with neonatal lupus and congenital heart block in newborns.

By identifying Anti-SS-A antibodies, physicians gain insight into autoimmune activity and can monitor patients more closely for systemic complications.
