Nonetheless, the reliability of these assays is of great importance in order to be useful as a tool in estimating the relative proportions of different populations that have been exposed to SARS-CoV-2. We provide a sampling of 145 individuals from an ambulatory setting simultaneously tested with a qualitative point of care rapid finger prick Lateral Wave® IgM and IgG assay and a sample for the Mayo Clinic enzyme linked immunosorbent assay (ELISA) IgM/IgG antibody assay. Significant discrepancies did exist between the purported antibody responses as demonstrated by each assay. To investigate the course of biomarkers on admission and follow-up in order to identify early predictors for poor outcome in COVID-19 patients. In this study, 132 COVID-19 patients were classified as good outcome (n=62) and poor outcome (n=70) groups. Laboratory parameters were evaluated on admission and within 5-7 days after hospitalization. Baseline levels of neutrophil-lymphocyte ratio, CRP, procalcitonin, ferritin, D-dimer and LDH were higher ( <0.01); lymphocyte count was lower in the poor outcome patients. During follow-up there was a larger decrease in lymphocyte count and more prominent increases in other biomarkers ( <0.001). In ROC analysis, the AUCs strongly indicated the poor outcome on days 5-7 of the hospitalization. This study suggests that the follow-up measurements of the biomarkers better predict the poor outcome in COVID-19 pneumonia.
