Olympus has launched sensitive and precise PSA and fPSA assays for the Olympus AU3000i immunoassay analyser. The use of PSA and fPSA is well established in the screening and management of prostate cancer. Olympus is joining this market with an extremely sensitive PSA assay with a functional sensitivity of 0.015μg/L. A recent multicentre evaluation of the analytical performance of the new Olympus PSA assay on the AU3000i has been undertaken involving the University Hospital
Munich Großhadern, the Hospital Nürnberg, and the C.H.U Montpellier. This study has demonstrated that the Olympus PSA assay showed ‘very good functional sensitivity’ and that the assay meets user needs and is suitable for use in the quantitative determination of PSA in human serum and lithium heparin plasma.
