CellSearch Cell Interpretation Objectives and Resources
This presentation discusses the method of operation and evaluation of cells in the CellSearch® system. The various biomarkers (CK-PE, DAPI, CD45-APC) are discussed as well as their appearance in tumor cells and non-epithelial cells. Suspicious objects, computer noise, and other distractor objects are also evaluated. The criteria for counting tumor cells, evaluating slide quality, and analyzing control samples are given as well.
