Clinical Significance

JC Polyoma Virus (JCV) is the cause of progressive multi- focal leukoencephalopathy (PML), a demyelinating neurologic disease of immunosuppressed patients. This test detects JC polyoma virus DNA in CSF. Detection of the virus in specimens from AIDS and other severely immune compromised patients may indicate disease. Serum antibodies are not helpful in diagnosing PML as antibodies are common in the general population. JCV can also be detected in the urine of 3% of pregnant women, but is not associated with proven disease.
