Patient Instructions

Reference Range

<=0.90 = Negative, no detectable antibody.
0.91-1.09 = Equivocal, results inconclusive; submit new specimen.
>=1.10 = Positive, indicative of current or recent infection.
The results of ELISA performed on serum from immunosuppressed patients must be interpreted with caution.

Negative test results cannot rule out the possibility of an active Herpes zoster infection, but positive results are confirmatory.

The presence of IgM antibody in neonate’s serum can be considered indicative of congenital infection only if there has not been placental leakage.

This test is not intended for the determination of immune states. It is intended for the determination of person’s antibody response to indicate active infection to VZV (primary or reactivation) and not an indication of immunity.

Methodology

Enzyme-Linked Immunosorbent Assay (ELISA)
