Clinical Information

C Polyoma Virus DNA, Qualitative Real-Time PCR, Serum or Plasma - JC polyoma virus is the cause of progressive multifocal leukoencephalopathy (PML), a demyelinating neurologic disease of immunosuppressed patients. This test detects JC Polyoma Virus DNA in serum or plasma. Detection of 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.
