26029 Stratify JCV ™ Ab (w/Index) w/Rflx to Inhibition Assay (91665)

Stratify JCV ™ Ab (w/Index) w/Rflx to Inhibition Assay (91665)
Test Code: STJCVSO
Synonyms/Keywords
Stratify JCV Antibody & Reflex Inhibition (91665), JC Polyoma Virus Ab
Test Components
Index Value
JCV Antibody
Useful For
The 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.
