Low Anti-La/SSB antibody: what it means
A Anti-La/SSB antibody result below the normal range is considered low. Here is what a reduced 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

- Negative — the expected result; makes Sjögren's less likely but does not exclude it, particularly as anti-Ro can be positive with anti-La negative.
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.
