Patients with pulmonary sarcoidosis do not appear to be at increased risk for worse outcomes associated with COVID-19, but these patients may have a higher risk of COVID-19-related morbidity given the population’s increased prevalence of risk factors for severe disease, according to research findings published in …

2. For patients with suspected ILD who undergo BAL, we recommend that a differential cell count be performed on the BAL ・Ｖid. This includes macrophage, lymphocyte, neutrophil, and eosinophil cell counts. The remaining sample may be used for microbiology, virology, and/or malignant cell cytology laboratory testing if clinically indicated.
How are BAL results interpreted in clinical practice?
In clinical practice, a BAL result obtained in an individual patient is compared with the pattern expected for a suspected disease, and the results are then put into the diagnostic puzzle as far aspossible.
