To quote my MD friend " to make sure it worked" but here are some quick facts I learned today (from Quest Diagnostics link included prev.).MarkSturtevant wrote: ↑Sun Apr 11, 2021 4:12 pmI don't know why its advisable to check for the presence of antibodies after the vaccine. We don't do that for other vaccines. Is there a possibility that it would come out negative?
SARS-CoV-2 antibody testing can be used to:
-Identify SARS-CoV-2-infected persons with negative results on nucleic acid amplification (NAAT)/PCR tests, especially patients who present late with RNA levels below the detection limit of a NAAT/PCR assay, or when respiratory tract sampling is not possible
-Identify individuals who have been infected with SARS-CoV-2 and have mounted an immune response
-Identify individuals who may have an immune response to a recent or prior infection, or a potential immune response to a spike-targeted vaccination
-Assess how many people have been infected with SARS-CoV-2 in a population by identifying individuals who have developed antibodies to the virus
-Possibly help identify individuals who may be able to donate convalescent plasma as a possible treatment for those who are seriously ill from COVID-19
The presence of IgG or IgM antibodies to SARS-CoV-2 indicates that the patient has mounted an immune response to the virus. Although the immune response may protect against reinfection, this has yet to be conclusively established.
