Natera Prospera Kidney With Quantification
Natera has launched Prospera with Quantification, a cell-free DNA test for kidney rejection that provides the quantity of donor-derived cfDNA (dd-cfDNA), fraction of dd-cfDNA, and total cfDNA on every report. Combining these three metrics improves sensitivity when evaluating transplant rejection, compared to using dd-cfDNA fraction alone, Natera said. Currently, other commercially available cfDNA tests that assess transplant rejection only report the fraction of dd-cfDNA.
