Aim: Aim is to depict suggestive urine and stool parameters in asymptomatic suspected contact children living with COVID-19 infected adults. These parameters will facilitate identifying  children who deserve the confirmatory diagnosis of COVID-19 by PCR test.  Methods: Study was conducted in the National Hepatology and Tropical Medicine Research institute (NHTMRI) Cairo, Egypt. It included 66 mild COVID-19 adult patients (group1) and their 82 asymptomatic contact children (group 2). Results:  In group 1, both C reactive protein (CRP) and D-dimer levels were significantly high. C reactive protein was significantly positively correlated with urinary microalbumin> 30, albumin/ creatinine ratio and urine pus >10 cells / HPF and significantly negatively correlated with vitamin C. D-dimer was significantly negatively correlated with vitamin C. In group 2, CRP and D-dimer were significantly negatively correlated with urine specific gravity (SG), urinary vitamin C. CRP was significantly negatively correlated with stool pus > 10 cells/ HPF, while D-dimer was significantly positively correlated with stool occult blood.   Receiver Operating Curve (ROC) analysis revealed that urine SG showed the highest area under the curve (AUC); 0.859, 0.96, sensitivity of 100%, 100% and specificity of 71.8%, 77.8% with reference to D-dimer and CRP; respectively. Conclusions: In contact children of adult COVID-19 proved infection, urine SG, stool occult blood and stool pus > 10 cells/ HPF can be feasible tool for suspected COVID-19 infection, based on its results COVID-19 PCR request can be an imperative option to confirm the diagnosis; particularly in developing countries where detection of COVID -19 by PCR is not readily feasible.
