cord-283173-s3nb11je	Osman, Jennifer	Rapid screening of COVID‐19 patients by White blood cells scattergrams, a study on 381 patients	2020-06-15		.txt	text/plain	1383	97	49	We identified a specific "sandglass" aspect on the white blood cells scattergram of COVID‐19 patients reflecting the presence of circulating plasmacytoid lymphocytes. CBC analyzers such as SYSMEX ® (Japan), provide a white blood cells (WBC) differential fluorescence (WDF) scattergram, displaying a classification of WBC based on their morphology and their intracellular components. Patients admitted at Versailles Hospital suspected of having COVID-19 were eligible if symptoms were present for 3 or more days and if RT-PCR and a chest CT were performed (Supplementary This observation was reinforced by the presence of circulating plasmacytoid lymphocytes on blood smears from patients with COVID-19 whereas large hyperbasophilic lymphocytes, normally seen in other viral infections, were absent Complete characteristics of patients are reported in Table 1 . Based on this retrospective study, we conclude that WDF analysis can be implemented during the SARS-CoV-2 pandemic to quickly categorize symptomatic patients as either COVID-19 probable or improbable, depending on the presence of the plasmacytoid lymphocytes cluster on their scattergram.	./cache/cord-283173-s3nb11je.txt	./txt/cord-283173-s3nb11je.txt
