Diagnostic criteria
A confident diagnosis of AEP can usually be made without a lung biopsy in patients who meet the following criteria [7,8,58,62]:
●A febrile illness of short duration (one month or less, but often less than one week)
●Hypoxemic respiratory failure (eg, pulse oxygen saturation [SpO2] <90 percent on room air or arterial oxygen tension [PaO2] <60 mmHg)
●Diffuse pulmonary opacities on chest radiograph
●BAL differential cell count showing eosinophilia >25 percent
●Absence of known causes of eosinophilic pneumonia, including drugs, infections, asthma, or atopic disease (table 1) (see "Causes of pulmonary eosinophilia")
