The influence of age on induced sputum differential cell counts in normal subjects.
STUDY OBJECTIVES: Sputum induction is increasingly used as a research technique and as a clinical tool. In order to evaluate abnormal results, normal ranges need to be fully developed. Although a number of studies have described normal ranges, none have investigated the effect of the age of the subject on these results. This study was undertaken to assess whether there are age-related differences in sputum cell differential cell counts in a population of normal, healthy volunteers. STUDY DES...Expand abstract
