Reportable range for this assay is 1,000-999,000 HHV6 DNA copies/mL (3.0-6.0 log copies/mL).
Quantitative Polymerase Chain Reaction (PCR).
This assay aids in the diagnosis of roseola infantum (infection subitum) and other HHV-6 infections.
HHV-6 is the causative agent of roseola. Roseola is characterized by the abrupt onset of a high fever which is followed in 2-4 days by erthematous maculopapular rash that lasts for 1-2 days. Roseola lesions are macular or papular and never become vesicular like the lesions associated with VZV or HSV. Lesions typically appear on the neck and back and then spread to the abdomen and thighs. The syndrome is self-limiting but convulsions associated with high fever can cause permanent neurologic injury. Atypical roseola can occur in the absence of rash. (1)
