Our current provider of polyomavirus John Cunningham virus-like particles (JC VLPs) for serology assays is unable to provide us with suitable antigen, and to date we are unable to source from another provider. We are therefore currently unable to provide JCV antibody testing and we have suspended this service until further notice.
Testing for John Cunningham virus (JCV) DNA by PCR remains unaffected.
