JC Polyoma Virus is the cause of Progressive Multifocal Leukoencephalopathy (PML), a severe demyelinating disease of the central nervous system, particularly affecting individuals with HIV. Quantitative measurement of JC virus DNA in urine via real‑time PCR supports clinical diagnosis and monitoring; the assay’s reportable range spans approximately 50 to 50,000,000 IU/mL (1.70 to 7.70 log IU/mL).
