Moreover, a cross-sectional study that evaluated the clinical course of maternal mortality cases due to severe forms of COVID-19 indicated a higher frequency of leukocytosis with raised neutrophils: lymphocytes ratio, thrombocytopenia and elevated levels of acute phase reactants and inflammatory markers such as CRP, serum ferritin, lactate dehydrogenase (LDH), D-dimer, and serum fibrinogen in their cohort of unvaccinated patients [24]. The gene discussed is CRP; the disease is Increased total leukocyte count.
