Determination of D-dimer, iron, calcium, prothrombin time, ferritin and vitamin D3 in patients with COVID-19 in Iraqi peoples‏‏

The primary purpose of this study is to determine the prevalence and effectiveness of covid19 through biochemical testing of ferritin, D3, and iron levels in the presence of risk factors such as age and gender and clinical-pathological testing. Comorbidities showed a slightly significant difference between severe and non-severe cases compared to diabetes. Still, they were highly influential in the case of asthma and non-significant in the case of smoking and heart disease. In extreme cases, hypertension has a slightly significant effect compared to other groups. The most prevalent signs and symptoms of sars-covid19 were fever and dry cough (55 percent and 78 percent, respectively). The relationship between SARS-CoV-19 infection and white blood cell count was highly significant, with the highest percentage of severe cases showing a reduction in white blood cell count. This was equally true for patients who were not in critical condition. Our findings revealed a highly significant association between CRP and Ferritin in severe instances and vitamin D deficiency with calcium in severe cases when compared to healthy subjects. However, there was no correlation between Iron in both groups. Keywords: COVID-19, D-Dimer, Vitamin D3, Prothrombin time, Blood clotting
