Background: As Coronavirus disease 2019 (COVID-19) is a global pandemic infectious disease, medical staff all over the world are still struggling with the management of the disease. Biochemical and hematological changes can be considered as prognostic markers. Methods: A total of 65 Egyptian children positive covid-19 were enrolled, between 5-12 years. Results: White blood cell count was significantly low (mean= 4968±742.6, p≤0.001). Lymphocytopenia was significantly low (mean= 1529.9 ± 493.9, p≤0.001). N/L showed statistically significantly high (mean= 2.45± 0.72, p≤0.001), platelets showed statistically significantly low (mean= 196.7± 82.58, p≤0.001) both correlated to severity. Plat/Lymph showed a statistically significant difference between groups. CRP increased than normal (mean=12.14 ± 3.3, p≤0.001), and was negatively correlated with Lymphocyte %. D-dimer slightly increased than normal and showed statistical difference between groups. Conclusion: This study declares that pediatric COVID-19 showed various
prognostics as CRP, thrombocytopenia, lymphopenia, neutrophil-to lymphocyte ratio, platelet-to lymphocyte ratio. As they are easily accessible, the majority of labs not expensive and showed a very good correlation with prognosis.
