Research into Morphofunctional Characteristics of Erythrocytes in COVID-19 Patients

Abstract

In this paper, the erythrocytes of healthy donors and people with a confirmed diagnosis of COVID-19 were tested by Raman spectroscopy and laser interference microscopy. We argue that erythrocytes (red blood cells) in COVID-19 patients have an irregular shape, and their morphometric characteristics are impaired in comparison to healthy red blood cells. Raman spectroscopy also allows us to detect a decreased oxygen transport function of these erythrocytes. The combination of these methods-Raman spectroscopy and laser interference microscopy-is a highly effective method for the diagnosis of SARS-CoV-2.
