Changes in White Blood Cells, D-Dimer and Lactate Dehydrogenase Level in Covid-19 Patients A Comparative Study

Coronavirus is a new pandemic disease that began in Wuhan, China, and has since spread over the globe. The number of COVID-19 cases reported daily Iraq slowly increased. This study aims to investigate effect Covid-19 on normal range White Blood Cells (WBC), D-Dimer, Lactate Dehydrogenase (LDH). looked at 65 patients who had tested positive for SARS-CoV-2 using polymerase chain reaction analysis. Patients with mild symptoms CT scan chest were separated into three groups: those chest, intermediate presenting fever cough, other respiratory symptoms, severe disease. At time study, all patients' data collected from Al-Diwaniyah Teaching hospital admission parameters blood cell count, lactate dehydrogenase (LDH) levels, D-Dimer December 27, 2020, April 1, 2021. WBC LDH higher than control group (8.15 X109/L versus 390 ng/ml 593 U/L), respectively, difference was highly significant (p < 0.001). There no count among according severity > 0.05). A larger leukocyte increased risk death. These signs can reliably predict patient's prognosis while hospital. Our study's best lab marker LDH.
