Examination of the relationshıp between blood values and mortality of Covid-19 positive patients: a retrospective analysis

Aim: Many factors affect mortality rates due to COVID-19. COVID-19 causes many changes in patient blood parameters. Therefore, in our study, we aimed to evaluate whether there is a relationship between the analysis of basic laboratory findings of COVID-19 patients admitted to the emergency department and mortality due to COVID-19. *.%%3%.&.:&&.3- <) /..&..&.3&.'+. F'&. Material-Method: The blood measurement values of the patients admitted to the emergency department with the diagnosis of COVID-19 were evaluated retrospectively. The progress of the patients was examined electronically and recorded as recovery and death. A total of 3965 patients were included in the study, and patients with radiologically positive but negative PCR tests were not included in the study. Results: A statistically significant difference was found in the levels of leukocytes, lymphocytes, HGB, MPV, Basophils, Neutrophils, CRP, PTZ, INR and paCO₂, whether the patients were healthy or deceased (p0.05). According to these findings, high Mean Platelet Volume, Leukocyte, Basophil, Neutrophil, CRP and PaCO2 values and low Lymphocyte, Hemoglobin, PTZ and INR values were evaluated as a significant relationship with mortality. Conclusion: We evaluate that leukocytes, neutrophils and lymphocytes, CRP, clotting times and anemia are important parameters for predicting mortality rates from COVID. It should be known that close follow-up of COVID patients with these parameters will be beneficial
