Clinical Info
JC polyoma virus is the cause of progressive multifocal leukoencephalopathy (PML), a demyelinating neurologic disease of immunocompromised patients and patients on certain medications. This test detects and quantifies JCV in CSF, and detection of the virus in CSF may indicate infection.
