The Roche Elecsys HSV-1 IgG immunoassay is a test for the in vitro qualitative determination of IgG class antibodies to HSV-1 in human serum and lithium-heparin plasma, K2-EDTA plasma, and K3-EDTA plasma. The test is intended for sexually active individuals and expectant mothers as an aid in the presumptive diagnosis of HSV-1 infection. The predictive value of positive and negative results depends on the population's prevalence and the pretest likelihood of HSV-1.
The electrochemiluminescence immunoassay "ECLIA" is intended for use on Elecsys and cobas e immunoassay analyzers.
This test is not FDA-cleared for screening blood or plasma donors.
The performance of this assay has not been established for use in a pediatric population, neonates, immunocompromised patients, or for use at point-of-care facilities.
PreciControl HSV is used for quality control of the Elecsys HSV-1 IgG immunoassay on the Elecsys and cobas e immunoassay analyzers.
Indications for use as stated in the FDA summary.
