Due to the paucity of basophils in bronchial lavage fluid and the lack of specific basophil detection and quantification methods, basophil\u2010directed research in these samples was hampered in the past. This study aimed to establish and validate a flow cytometry\u2010based basophil detection and quantification method for human basophils from bronchoalveolar lavage (BAL) and blood as a prerequisite for a better understanding of their pathogenic contribution and subtyping of asthma phenotypes. BAL and blood leukocytes from seasonal asthmatics were analyzed by flow cytometry. Chipcytometry, a highly sensitive single\u2010cell analysis method, was used to validate the staining panel for basophils. Cell differentials of May\u2013Gr\u00fcnwald\u2013Giemsa\u2010stained cytospins were used to compare basophil percentages. BAL basophils are identifiable as CD123<jats:sup>+<\/jats:sup>HLA\u2010DR<jats:sup>\u2212<\/jats:sup>CD3<jats:sup>\u2212<\/jats:sup>CD14<jats:sup>\u2212<\/jats:sup>CD19<jats:sup>\u2212<\/jats:sup>CD20<jats:sup>\u2212<\/jats:sup>CD56<jats:sup>\u2212<\/jats:sup> cells in flow cytometrical analysis. Their identity was validated by Chipcytometry. CD203c was highly expressed by BAL basophils, whereas it was expressed at variable levels on blood basophils. The two quantification methods correlated, although more basophils were detected by flow cytometry. Furthermore, the increase in basophil percentages in the lung correlated with the decrease in the basophil percentages in the blood after allergen challenge. We here validated a reliable basophil quantification method, which is independent of the cell's activation and degranulation state. The results obtained with this method indicate that basophils are directly recruited from the blood circulation to the airway lumen. \u00a9 2014 International Society for Advancement of
