Clinical trial CTC monitoring




Start your program Learn more about CTCs

Serial monitoring of circulating tumor cell (CTC) numbers and biomarker expression levels provides critical insight into cancer drug efficacy and pharmacodynamics.


Designed for CTC monitoring in global clinical trials, RareCyte’s products and services provide a sample-to-result workflow that accurately and reproducibly phenotypes as few as 1 CTC per tube of blood.


Phenotype CTCs with Confidence

RareCyte CTC assays cover an expansive range of biomarkers and indications, powered by RarePlex technology.

  • Rapid and flexible assay development and validation
  • Visual CTC confirmation assisted by ML/AI scoring system
  • Quantification of multiple biomarkers that inform response to therapy
  • Option for downstream single CTC genomic analysis
