Basic Biology and Detection of Cell-Free DNA

This webinar is a recorded presentation of a live broadcast and includes a pre-test, the presentation, handout, and a post-test. Continuing education credit is available for the webinar.

This interactive webinar is part 1 of the 8 part Utility of Cell-Free DNA in the Clinic Series.


In the rapidly evolving field of liquid biopsies, this first seminar will provide an overview of the current understanding of the biology of cell-free DNA and circulating tumor DNA in the context of healthy and benign conditions, and malignancy. Particular attention will be given to pre-analytical variables that affect the reliability of cell-free DNA assays and the clinical implications of these results.

Learning Objectives:
  • Describe typical cell sources, fragmentation, and quantities of cfDNA.
  • Recognize unique cfDNA analytes associated with specific conditions and diseases.
  • Summarize pre-analytical variables that affect recovery and detection of cfDNA.
