High Anti-La/SSB antibody: what it means
A Anti-La/SSB antibody result above the normal range is considered high. Here is what a raised Anti-La/SSB antibody can point to, and when it is worth discussing with a doctor.
Reference range: Typically <7 U/mL negative (assay-dependent); usually seen together with anti-Ro/SSA and supports Sjögren's syndrome
Understand your full resultWhat a high Anti-La/SSB antibody can mean
- Sjögren's syndrome — the main association, especially together with anti-Ro/SSA, with dry eyes and mouth.
- Lupus — sometimes present, usually alongside anti-Ro.
- Typically seen with anti-Ro — a positive anti-La almost always accompanies a positive anti-Ro.
- An isolated anti-La positive — uncommon and of less certain significance.
When to discuss with a doctor
Anti-La/SSB is tested as part of the antibody work-up when Sjögren's syndrome or another connective-tissue disease is suspected — for example with persistent dry eyes and dry mouth, joint aches and a positive ANA. A positive anti-La, especially together with anti-Ro, supports Sjögren's, but it is always interpreted with the clinical picture by a rheumatologist rather than in isolation. Diagnosis usually combines the antibodies with symptoms and sometimes eye and gland tests. Mediora.AI can surface a positive anti-La alongside anti-Ro and ANA so the Sjögren's pattern is visible in your results, but confirming the diagnosis and planning care belongs with your doctor and rheumatologist.
