Positive: Antibodies to JC virus (JCV) detected indicating the patient has been exposed to JCV at an undetermined time. Negative: Antibodies to JCV not detected. The STRATIFY JCV Antibody Test is an enzyme-linked immunosorbent assay (ELISA) designed to detect JCV antibodies to help identify individuals who have been exposed to the virus.
