Term Description

California encephalitis virus has more than 20 strains, most of which include "strain" in the name. In some cases such as La Crosse virus, however, the name does not signal that it is a strain of California encephalitis.

Part Descriptions

LP14236-1   La Crosse virus
La Crosse virus is a mosquito-borne virus causing encephalitis in the United States at higher rates than bacterial meningitis. The disease is recurrent during warm seasons in the Mid-West and mid-Atlantic whose hardwood trees provide breeding sites for the mosquito species Aedes triseriatus. Testing for La Crosse virus should be perfomed on young patients with symptoms of encephalitis in these two parts of the United States during the summer and fall.

LP14236-1   La Crosse virus
La Crosse encephalitis is an encephalitis caused by an arbovirus (the La Crosse virus) which has a mosquito vector (Ochlerotatus triseriatus synonym Aedes triseriatus).

Historically, most cases of LAC encephalitis occur in the upper Midwestern states (Minnesota, Wisconsin, Iowa, Illinois, Indiana, and Ohio). Recently, more cases are being reported from states in the mid-Atlantic (West Virginia, Virginia and North Carolina) and southeastern (Alabama and Mississippi) regions of the country.

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.

Change Reason
Release 2.72: COMPONENT: Updated "Ab" to "Ab.Neut" since this test is detecting neutralizing antibodies.; Previous Releases: The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
