PURPOSE: Early diagnosis of OAD can reduce morbidity and mortality as usually the symptoms appear at much later stage when disease has progressed significantly. Spirometry is rarely recommended as a routine test during annual health checks. In this study we aimed to address the importance of spirometry as an important screening tool for the early diagnosis of obstructive airway disease.
