Grossly hemolyzed, lipemic, or icteric specimens will be rejected. The STRATIFY JCV Antibody and Index with Reflex to Inhibition will be performed at no charge. Interpretive criteria: Negative: < 0.20; Indeterminate: 0.20 - 0.40; Positive: > 0.40. If reflexed, turnaround time may be extended.
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.
