  1. Comparative study was performed between Avenio ctDNA Expanded kit and TruSight500 ctDNA kit using 12 cancer specimens collected from patients diagnosed with Breast cancer (stage IIB), Colorectal Cancer (Stage III-IV), NSCLC (stage II-III) and Prostate Cancer (Stage III-IV)
  2. aTwo of the 12 samples did not give enough cfDNA for testing using TruSight500 ctDNA kit
