Test Indications:
|
Human herpesvirus 6 (HHV-6) infects peripheral blood leukocytes, and is considered the agent of roseola. The normal prevalence of HHV-6 antibody is high; nearly 100% of the population will demonstrate antibody at midlife with titers declining in old age. Immunofluorescence assays are used for serological detection of HHV-6. Crossreactions with other Herpes viruses, i.e., Cytomegalovirus and Herpes Simplex have not been found. In order to demonstrate primary infection, it is necessary to detect a significant change in titer.
