Ki67-QC calibrator available to public

The Ki67-QC calibrator is a web-based calibration exercise designed to calibrate pathologists to a prescribed scoring method. Nine “training” and nine “test” tissue microarray cases representing a wide range of Ki67 scores were chosen to serve as the calibration cases.

This website interface allows pathologists to score the web-image cores via computer mouse click on individual cells. The website software tracks which cells were scored, where those cells were located within the core, whether each cell was scored positive or negative, and the overall Ki67 score for each core. Images of H&E-stained sections from the cores were also uploaded for reference.
