Setup Schedule
Set up: Daily; Report available: 1 day

Reference Range
Not detected

Clinical Significance
This test is used to determine the presence of HHV-6 DNA in patients' specimens. Organisms may be detected by PCR prior to detection by immunological methods. PCR provides more rapid results than other methods, including culture.
