0.90-1.09 IV: Equivocal - Questionable presence of IgG antibodies. Repeat testing in 10-14 days may be helpful.
1.10 IV or greater: Positive - IgG antibody to HSV detected which may indicate a current or past HSV infection.
Fourfold or greater rise in CSF antibodies to herpes on specimens at least 4 weeks apart are found in 74-94% 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.
