LP14232-0   Saint Louis encephalitis virus
St. Louis Encephalitis is a disease caused by the mosquito borne St. Louis Encephalitis virus. St. Louis encephalitis virus is related to Japanese encephalitis virus. This disease mainly affects the United States. Occasional cases have been reported from Canada and Mexico. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

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

LP6416-4   Neut
In LOINC, the Method "Neut" represents the virus neutralization test (VNT), also called conventional VNT, which is a specific laboratory method that is used primarily for identifying whether neutralizing antibodies for the virus of interest are present in the patient sample. The VNT involves incubating patient serum with the virus of interest, and then inoculating onto cell culture. If neutralizing antibodies are present and the virus is neutralized, the cells will not be infected. If neutralizing antibodies are not present, the virus will infect the cells in the cell culture. PMID: 32170698 This method can also be used to identify specific virus serotypes or strains, by performing separate tests in which serum is incubated with each of the specific virus serotypes or strains of interest. PMID: 169804 Source: Regenstrief LOINC
