GenScript’s SARS-CoV-2 Neutralizing Antibody Rapid Test uses novel technology to detect antibodies specific to the spike protein receptor binding domain (S-RBD) of the SARS-CoV-2 virus responsible for COVID-19. Antibodies to this specific antigen are generated by the body via two methods 1) natural infection or 2) vaccination. The S-RBD is the critical viral component used by the virus to enter human cells and is the primary target used in vaccine development to illicit a specific immune response. Detecting the presence of the neutralizing antibodies is the first step in determining whether there is an adaptive immune response!

Samples from a cohort of patients were tested using the SARS-CoV-2 Neutralizing Antibody Rapid Test Kit. The combined cohort consisted of samples from normal healthy people (n= 25) and samples from confirmed SARS-CoV-2 positive patients (n=25) based on plaque reduction neutralization test (PRNT) results.
