Significance: HHV-8 can be an important pathogen causing encephalitis and meningitis. Prompt recognition of the presence of HHV-8 is helpful for clinical differential diagnosis. Cell cultures have not been reliable for recovering this virus from cerebrospinal fluid (CSF). Detection of HHV-8 DNA in CSF is now the gold standard for the laboratory diagnosis of central nervous system diseases caused by this virus. HHV-8 testing can be used to confirm Kaposi sarcoma in tissue materials.
Special Instructions: Other sources / samples may be acceptable for this test; please check with the lab, 615-936-6435.
