Varicella-Zoster Antibody, IgG, Serum
Use
This test is useful for the determination of immune status of individuals to the varicella-zoster virus (VZV). It aids in documenting previous infection with VZV in individuals without a previous record of immunization to VZV. The presence of detectable IgG-class antibodies indicates prior exposure to the varicella-zoster virus (VZV) through infection or immunization. Individuals testing positive are considered immune to varicella-zoster. Vaccinated individuals show a positive antibody index, while unvaccinated individuals show a negative index.
Special Instructions
Not provided.
Limitations
Immunoglobulin G-class antibodies to varicella-zoster virus may be present in serum specimens from individuals who have received blood products within the past several months but have not been immunized or experienced past infection with the virus. Serum specimens drawn early during the acute phase of infection may be negative for IgG-class antibodies to this virus. This test is for qualitative purposes only; the numeric value of the antibody index is not indicative of the amount of antibody present.
