26279 COVID19, SARS-CoV-2 IgG Antibody

COVID19, SARS-CoV-2 IgG Antibody
Test Code: COV19IG
Synonyms/Keywords

COVID-19, Coronavirus, SARS-CoV-2, Antibody IgG, COVID19, SARS-CoV-2 IgG, COV19AB

Test Components

SARS-CoV-2 IgG

Useful For

This test is designed for detection of antibodies to SARS-CoV-2 in plasma from individuals suspected to be recovering, or recovered, from COVID-19 by their healthcare provider. It can be used to:

·         Identify potential convalescent plasma donors

·         Support diagnosis of acute COVID-19 illness in persons who present late. For persons who present 9–14 days after illness onset, serologic testing can be offered in addition to the recommended viral direct detection methods

·         Support a diagnosis when patients present with late complications of COVID-19 illness, such as multisystem inflammatory syndrome in children

·         Support epidemiologic studies and for surveillance purposes, such as understanding the transmission dynamics of the virus in the general population
