Reference Interval
0.89 IV or less: Negative - No significant level of detectable IgG antibody to HSV type 1 glycoprotein G.
0.90-1.10 IV: Equivocal - Questionable presence of IgG antibody to HSV type 1. Repeat testing in 10-14 days may be helpful.
1.11 IV or greater: Positive - IgG antibody to HSV type 1 glycoprotein G detected, which may indicate a current or past infection.
Interpretive Data
Individuals infected with HSV may not exhibit detectable IgG antibody to type-specific HSV antigens 1 and 2 in the early stages of infection. Detection of antibody presence in these cases may only be possible using a nontype-specific screening test.

The detection of antibodies to herpes simplex virus in CSF may indicate central nervous system infection. However, consideration must be given to possible contamination by blood or transfer of serum antibodies across the blood-brain barrier.

Fourfold or greater rise in CSF antibodies to herpes on specimens at least 4 weeks apart are found in 74-94 percent of patients with herpes encephalitis. Specificity of the test based on a single CSF testing is not established. Presently PCR is the primary means of establishing a diagnosis of herpes encephalitis.
