What focus score diagnoses Sjögren's?

Focus score ≥1 = ≥1 lymphocytic focus per 4mm² evaluable gland tissue, where each focus is an aggregate of ≥50 lymphocytes. Focus score ≥1 scores 3 points on the ACR/EULAR 2016 classification criteria.

What does the ACR/EULAR 2016 Sjögren's criteria include?

Total score ≥4 required: lip biopsy focus score ≥1 (3 points), positive anti-SSA/Ro (3 points), Schirmer test ≤5 mm/5 min (1 point), unstimulated salivary flow ≤0.1 mL/min (1 point), ODISSEY/OSDI ocular symptoms (1 point).

Is anti-SSA positive required for Sjögren's diagnosis?

Not strictly required if focus score ≥1 and ocular/oral dryness criteria are met (achieving ≥4 points by other means). However, anti-SSA is the most specific serological marker for pSS.
