Analytical evaluation of the testosterone assay on the Bayer Immuno 1 system.

Objectives: To evaluate the analytical performance of the testosterone assay performed on the Bayer immuno 1 system from Bayer Corporation.

Design And Methods: The precision was measured using three Bayer TESTpoint Ligand controls, three Medical Decision Pools and the Bayer SETpoint Testosterone calibrators. The linearity was verified by diluting two serum samples containing high testosterone concentrations with the zero calibrator and the minimum detectable concentration determined by repetitive analysis of the zero calibrator.
