Circulating Tumor DNA Sequencing Service – Colorectal / Lung / Breast

Discover and Accelerate with Reliable result

Highly Optimized Panel for Clinical Testing with Exceptional Accuracy


The detection sensitivity for low-frequency variants from a limited
amount of sample is of a great importance of ctDNA analysis kit.

Celemics has developed ctDNA kit for colon, breast, lung cancer assay through a collaborative
research with Seoul National University Hospital (SNUH) since 2017.
We have integrated our market leading proprietary technologies including probe design
algorithms, noise removal techniques, and reagents optimization.
The panel is thoroughly validated and ready to use for clinical diagnosis.

Workflow of Celemics’ Circulating Tumor DNA Panel

  • Able to assess ctDNA with ultra-low variant allele frequency (VAF)
  • Modular algorithm to be applied in the existing pipeline.
  • Retrieves more unique reads than that from conventional duplication
    removal algorithm reducing sequencing costs
  • Noise removal and accurate calls due to proprietary consensus sequence
    generation algorithm

Bioinformatics SW for noise reduction and duplicate read recovery

  • Minimizes the noise for accurate analysis of variants with ultra-low VAF from ctDNA
  • Generates consensus read to support noise suppression
  • Continuous improvement of the noise removal technology by data accumulation
