  Objective: About 80% of corona virus disease-19 (COVID-19) deaths due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection occur in subject’s ≥ 65 years of age, even though subjects in this age group only account for about 10% of COVID-19 cases. Our objectives were to assess age effects and the clinical utility of COVID-19 antibody levels in health, disease, and post-vaccination. Methods: We measured serum SARS-CoV-2 immunoglobulin M (IgM), IgG and neutralizing antibodies using immunoassay kits obtained from Diazyme (Poway, CA) and spike (S) protein antibodies using immunoassay kits obtained from Roche Diagnostics (Indianapolis, IN). Results: In 79,005 subjects, IgG and IgM levels were positive (≥1.0 arbitrary units [AU]/mL) in 5.29% and 3.25% of subjects, respectively.. View more»
