Version 2.77

Term Description

Qualitative results for detection of neutralizing antibodies (NAbs) that block the binding of the S (spike) protein receptor binding domain (RDB) from SARS Coronavirus 2 (SARS-CoV-2) to ACE2 receptor protein in serum or plasma specimens by surrogate virus neutralization testing (sVNT), which is an immunoassay-based method. Neutralizing antibody testing is performed to determine whether the antibodies produced after SARS-CoV-2 infection or in response to a vaccination are able to neutralize the virus and prevent infection or re-infection. Different methods can be used to determine the presence of neutralizing antibodies, including conventional VNT (virus neutralization test, cVNT), pseudovirus VNT (pVNT), and surrogate VNT (sVNT). The sVNT method currently employs purified proteins in an immunoassay-based format, takes less time to complete, and does not require the use of live virus compared to cVNT and pVNT methods.

Part Description

LP207365-0   Ab.Neut
Neutralizing antibodies are antibodies that interfere with the interaction between the virus and its host cell receptor, therefore preventing infectivity. Neutralizing antibodies can be detected using a traditional VNT or other methods such as pseudovirus VNT and surrogate VNT. VNT and pseudovirus VNT use live virus (the actual virus or a recombinant virus that incorporates the viral antigen of interest, respectively) and cell culture to assess the virus-host interaction and whether neutralizing antibodies are present that block that interaction. Surrogate VNT (sVNT) does not use live virus but rather uses purified viral antigen and host cell receptor protein to mimic the same interaction. The sVNT method is currently (2021) represented in LOINC as IA, because it is an immunoassay-based method. Source: Regenstrief LOINC
