Eosinophilic distribution pattern in nasal secretions of patients with nasal allergy [in children and adults]

The distribution of eosinophils within the nasal cavities in 20 patients with perennial allergic rhinitis was compared to 10 healthy control subjects by taking nasal smears from 3 sites in each side of the nose: middle and inferior turbinates and post nasal space. Serum IgE levels were estimated and those above 100 IU/ml were only chosen for comparison with the level of Eosinophilia. Smears were significantly correlated with the serum IgE. Post-nasal space has been proved statistically to be the site of choice [p > 0.001] for detection of representative sampling for more accurate eosinophil expression
