label_lc: elevated bronchoalveolar lavage fluid eosinophil proportion
description: "Usually, eosinophils make up less than 0.5% of all cells found in the broncho-alveloar lavage fluid. But in eosinophilic lung disease, the eosinophil cell proportion typically represents more than 25%. Comment: An elevated level of eosinophil cells are also a result of infections, or an allergic reaction or can be drug-induced."
