COPENHAGEN, Denmark--(BUSINESS WIRE)--Unilabs has been selected by Biogen Idec to provide a companion diagnostic anti-JCV antibody assay test, called STRATIFY-JCV. The test is a highly sensitive two-step ELISA assay used to detect anti-JCV antibodies. The presence of anti-JCV antibodies is one in a three-factor risk stratification algorithm, along with prior immunosuppressant use and treatment duration, used to calculate the risk of TYSABRI-treated patients developing progressive multifocal leukoencephalopathy (PML).
