Special Info

This assay will be performed at no charge. If the Index Value is between 0.20-0.40 (inclusive), then Stratify JCV™ Antibody Inhibition Assay will be performed. If reflexed, turnaround time may be extended. Grossly hemolyzed, lipemic, or icteric specimens will be rejected.

Clinical Info

JC Virus (JCV) is associated with progressive multifocal leukoencephalopathy (PML). Detection of antibodies to JCV in serum or plasma is a reliable indicator of exposure to JCV. The analytical performance characteristics were determined for multiple sclerosis patients. Interpretive criteria: Negative: < 0.20; Indeterminate: 0.20 - 0.40; Positive: > 0.40.
