Neutralizing Antibody Test
SARS-Cov-2 Neutralizing Antibody Test
CoreBioLabs’ Covid-19 Neutralizing Antibody Test is for qualitative testing of human blood and serum for the presence of neutralizing antibodies to SARS-CoV-2 virus. Neutralizing antibodies are like the special forces of the immune response disarming the virus at just the right point before it can attack our cells. Neutralizing antibody levels are highly predictive of immune protection from symptomatic SARS-CoV-2 infection. Many different antibodies are elicited from SARS-CoV-2 infection or vaccination but only a subset handcuff the virus so it can’t take control of the cells and spread.
Recent studies have identified a decline in neutralization titer with time for up to 8 months after SARS-CoV-2 infection. However, the duration of protective immunity is presently unclear, primary immune responses varies of increasingly concerning viral variants. Vaccine efficacies from 50 to 95% have been reported; a major question is whether vaccine-induced responses may be more durable than those measured following infection.
