What does a positive HSV-1 or HSV-2 IgG result mean? A positive result strongly suggests a recent or past HSV infection. The person may be capable of transmitting the virus to others. A small percentage of positive HSV-2 IgG results may be false-positive.1 Further testing may be appropriate for patients with a low or unexpected positive HSV-2 IgG result. The HSV-2 IgG Inhibition, ELISA performed at Focus Diagnostics Reference Laboratory can be used to further characterize the sample and distinguish a false-positive from a true-positive result.
