title: Relative value of peripheral blood, secretion and tissue eosinophilia in the diagnosis of different patterns of allergic rhinitis.
abstract: Eosinophil count in peripheral blood, nasal secretion and nasal mucosa were studied in 20 controls and 38 patients with different patterns of allergic rhinits. Secretion and tissue eosinophilia were pathologically high in a greater number of patients than peripheral blood eosinophilia. This trend was seen in all patterns of allergic rhinitis but was more evident in seasonal allergic rhinitis. The conclusion was reached that examination of local site and local secretions for eosinophilia is helpful in the diagnosis and differential diagnosis of allergic rhinitis.
