Test Overview

Test Methodology

Chemiluminescent Immunoassay

Test Usage

Support the diagnosis of Herpes simplex infection (type 1 or type 2). The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody indicates recent infection. Single IgG levels are not useful for supporting the diagnosis of an acute infection. Elevated levels in neonates should be followed up with studies to rule out the presence of maternal antibodies by demonstrating the absence of an IgM response.

Reference Range

NEGATIVE: No detectable IgG antibody to Herpes simplex virus. EQUIVOCAL: Presence or absence of IgG antibody to Herpes simplex cannot be determined. Another spcimen should be sent for analysis. POSITIVE: Detectable levels of IgG antibody to Herpes simplex. Detectable levels of Herpes simplex antibody indicate previous exposure to Herpes simplex virus.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
