What is the expected ccfDNA yield from plasma generated from 10 ml of blood?

The yield of ccfDNA depends on the target ccfDNA. Nevertheless, yields obtained from PAXgene Blood ccfDNA Tubes are comparable to those obtained from the same volume of plasma separated directly after drawing blood into a spray-dried EDTA tube. In the PAXgene Blood ccfDNA Tube, however, this yield remains stable for up to 7 days when the tube is stored at 15–25°C or for up to 24 hours when stored at 35°C. In contrast, genomic DNA is released from lysed and apoptotic cells in the unstabilized contents of the EDTA tube soon after blood draw.
