claim: serology confirms sars-cov-2 infection in pcr-negative children presenting with paediatric inflammatory multi-system syndrome
evidence_1: detection of anti-sars-cov-2 antibody responses in children with pims-ts.", "this therefore offers a widening of the value of serology in the identification and understanding of infections caused by sars-cov-2.", "serological responses were detected against purified near-full-length trimeric sars-cov-2 viral spike glycoprotein by elisa.", "below, we present findings demonstrating that children with pims-ts, who are pcr-negative for sars-cov-2, can present with very high levels of igg antibody to the virus.",
