Range of the normal value for included sputum cells in people living in Silesian region
open access
Abstract
Methods: One hundred healthy volunteers in age 17-79 without respiratory symptoms were examined. They had normal spirometry, no airways hyperresponsiveness to metacholine and no history of allergic diseases. The sputum was obtained from 85 people. Viability, total and differential cell counts was performed.
Results: The range of the normal values for induced sputum cells was following [mean (± SD)]: macrophages 49.3% (11.5-77.1%), neutrophils 48.5% (9.6-87.2%), eosinophils 0.8% (<4.8), lymphocytes 1.4% (<4.2%). Smoking and age of subjects influenced the number and percent age of cells in sputum.
Conclusions:Finding of high percent age of eosinophils(>4.8%) in sputum may be helpful in the diagnosis of asthma. Counting of neutrophils and other cells is of limited practical value.
