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.
