Analysis of tumors using liquid biopsy.

Characteristics:

  • NGS panel and analysis software to screen for the study of the main biomarkers of clinical interest in non-small cell lung cancer and other solid tumors.
  • Characterization of ctDNA obtained from a liquid biopsy sample.
  • SNV, indel, genetic fusion, and CNV detection in a single DNA sample.
  • Bioinformatic analysis with the Data Genomics software and semi-automated generation of reports, which include both functional and clinical classification of the variants.
  • Based on high sensitivity RNA-probe technology with UMI barcoding (unique molecular identifiers).
  • Mean coverage: 7300X, with mean coverage after UMI analysis: 2500X.
  • The specificity, sensitivity, and repeatability of this kit are >99% and reproducibility is >97%. Coverage (at a read depth >100X) and uniformity of bases covered at >20X is >96%.
  • Limit of detection: SNVs, indels and structural variants: 1%; CNVs: gains of 2.9 copies.
  • Compliant with ISO 9001 and ISO 14001 quality specifications regarding manufacturing materials.
  • CE-IVD-marked analysis software.

Turnaround time (TAT): 12 working days
