Interpretive Data
This test is intended to be used as a semi-quantitative means of detecting California Encephalitis Group virus-specific IgG in CSF samples in which there is a clinical suspicion of California Encephalitis Group virus infection. A positive result for IgG may suggest current or past infection. This test should not be used solely for quantitative purposes, nor should the results be used without correlation to clinical history or other data. La Crosse virus is related within the California Encephalitis Group and generally is reactive with antibody to other viruses within this group.

The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use.
