What is the CELLSEARCH® System?


The CELLSEARCH® System is the first and only clinically validated, FDA-cleared system for identification, isolation, and enumeration of circulating tumor cells (CTCs) from a simple blood test.


  • Detects and enumerates CTCs of epithelial origin (CD45-, EpCAM+, and cytokeratins 8, 18+, and/or 19+) from a 7.5-mL blood sample with a high level of sensitivity and specificity.1
  • Provides rapid, precise, and reproducible analysis of CTCs with a simple 3-step process: sample collection, sample preparation, and sample analysis using unique immunomagnetic and fluorescence imaging technology.
