We quantitated the lactoferrin concentration in the tear fluid in 50 patients of definite primary Sjögren's syndrome. We used LactoplateTM in the quantitation. The concentration averaged 1.08± 0.86 mg/ml. There was a marked negative correla-tion between lactoferrin concentration and RoseBengal staining scores (r=-0.6929). In two biop-sy specimens, tear lactoferrin concentration well reflected the pathological features in the lacrimal gland. The present method showed sensitivity of 72.2%, specificity of 78.6%, false positivive of 21.4% and false negative of 27.8% in the diagnosis of dry eye in primary Sjögren's syndrome. The findings show the usefulness of quantitation of tear lactoferrin with the present method in the diagnosis of dry eye in primary Sjögren's syndrome.
