Varicella-Zoster IgG AbRefer to report


Clinical Information: A negative result does not rule out acute infection. If exposure to varicella-zoster virus is suspected, despite a negative finding, a second sample should be collected and tested no less than one-two weeks later. A second sample should be collected and tested on patients with equivocal results. A positive result generally indicates exposure to the pathogen or administration of specific immunoglobulins, but is no indication of active infection or stage of disease. The results are not by themselves diagnostic and should be considered in association with other clinical data and patient symptoms. Screening of the general population leads to no appreciable diagnostic advantage. The performance characteristics with individuals vaccinated with VZV (ROD strain) have not been established.

Limitations: The magnitude of the measured result is not indicative of the amount of antibody present. Results from immunosuppressed patients should be interpreted with caution.
