WebAbstract. Fragment size distribution, the important biological properties of cell-free DNA (cfDNA), provides useful information required for diagnostic assay development. However, besides methodological discrepancies, it varies due to the complicated origins and occurrences of in vivo cfDNA. Circulating free DNA (cfDNA) are degraded DNA fragments (50 - 200 bp) released to the blood plasma. cfDNA can be used to describe various forms of DNA freely circulating in the bloodstream, including circulating tumor DNA (ctDNA), cell-free mitochondrial DNA (ccf mtDNA), cell-free fetal DNA (cffDNA) and donor-derived cell-free DNA (dd-cfDNA). Elevated levels of cfDNA are observed in cancer, especially in advanced disease. There is evidence that cfDNA become… raglan coast cheer
