Cleveland Diagnostics: Improving The PSA Test
Executive Summary
A new prostate cancer assay that uniquely defines blood-based biomarkers could restore confidence in the controversial PSA (prostate specific antigen) screening test. Cleveland Diagnostics Inc.’s PSA/SIA test detects cancer-specific changes to the three-dimensional structure of a PSA protein molecule, as opposed to merely measuring the amount of PSA in the blood via a standard PSA test.
