We completed a seroprevalence study of healthcare employees (HCW) employed in three Federal government run clinics in Mumbai. Skillet immunoglobulin Elecsys Anti-SARS-CoV-2 Assay (Roche Diagnostics, Rotkreuz, Switzerland) using recombinant proteins representing the nucleocapsid (N) antigen in dual antigen sandwich assay format was completed after up to date consent. A specificity is had by This check of 99.8% and 100% awareness for CRT-0066101 patients, a fortnight post-PCR confirmation.
