Description
In cases of clinically or laboratory diagnosed chicken pox or exposed herpes zoster, it may be necessary to determine the immune status of contacts, particularly in pregnant women and those who are immunocompromised. A contact�s VZV IgG status is determined using an enzyme linked fluorescent assay (ELFA). If a negative result is obtained, VZV immune globulin can be administered as soon as possible, to prevent or limit disease.
Also known as
