SIMPLE PERIPHERAL BLOOD SMEAR FINDINGS OF COVID-19 PATIENTS PROVIDE INFORMATION ABOUT THE SEVERITY OF THE DISEASE AND THE DURATION OF HOSPITAL STAY.

Abstract

A peripheral blood smear is an inexpensive, easily performed, and rapid test. Increased Pseudo-Pelger-Huet anomaly/mature lymphocyte rate suggests a severe stage disease, while high initial mature lymphocyte and monocytes with vacuoles rates at the time of diagnosis may be an indicator of shortened duration of hospitalization.
