ABSTRACT
Coronavirus disease emerged in Wuhan, China in December 2019 and led to worldwide pandemic in March 2020. Due to early diagnose, treatment and prevent transmission of COVID-19 disease, we need rapid laboratory tests and develop them. This paper focuses on serum Iron level in patients with COVID-19. We assess the serum Iron level due to the following reasons: I. Iron is a key part of hemoglobin structure in which is essential for providing Oxygen to the body organs, particularly for the patients with pulmonary involvement such as COVID-19. II. Iron deficiency can contribute to muscle weakness and reduction of respiratory capacity, at which increases the risk of deterioration of COVID-19 patients. III. Elevation in Hepcidin level (due to the increase in IL-6 level) in COVID-19 patients inhibits Iron absorption from intestinal lumen and blocks the Iron release from macrophages. IV. Iron is an essential element in infectious suppress and inflammatory process. We noticed that most of the patients, especially admitted to hospital due to the respiratory symptoms, have lower serum Iron level.
