Allergen bronchoprovocation: correlation between FEV1 maximal percent fall and area under the FEV1 curve and impact of allergen on recovery

BackgroundHouse dust mite (HDM) induces greater responses than other allergens during allergen bronchoprovocation (ABP) testing. The two standardized methods for reporting results of ABP tests are the maximal percent fall in forced expiratory volume in one second (FEV1, max; %) and the area under the FEV1 vs time curve (AUC; %FEV1 x min). The relationship between these methods has not been previously investigated.AimsWe aimed to measure the …
