Cell-free DNA in diagnostic applications

Circulating cell-free DNA (ccfDNA)

An important biomarker for non-invasive prenatal testing (NIPT) and liquid biopsy, circulating cell-free DNA (ccfDNA) is obtainable through a regular blood draw. ccfDNA from plasma has the ability to provide a breadth of information to researchers and clinicians.

Did you know?

  • ccfDNA is present in low quantity in blood
  • ccfDNA can be further diluted by genomic DNA (gDNA) from apoptotic or lysed blood cells
  • The type of anticoagulant and crosslinking reagents in blood collection tubes can impact the quality of ccfDNA

Standardize your preanalytical workflow with the PAXgene Blood ccfDNA Tube (CE-IVD)
to preserve the ccfDNA profile in your blood sample

Applications

Non-invasive prenatal testing (NIPT)

Clinicians and researchers in the field of non-invasive prenatal testing analyze fetal DNA present among maternal ccfDNA from blood of a pregnant woman to determine the risk that the fetus will be born with certain genetic abnormalities.

Liquid Biopsy

Liquid biopsy is a minimally-invasive method of collecting a patient biofluid sample to test for biomarkers of disease. Liquid biopsy is commonly used for many applications in cancer research and diagnostics.
