Groundbreaking new dd-cfDNA results from the Trifecta Study
The publication demonstrates that a test using a two-threshold algorithm – based on donor fraction and estimated amount of donor-derived cfDNA – can significantly improve the identification of active rejection, compared to either variable alone.
The Trifecta study represents the largest multisite, prospective, fully biopsy-matched cohort with dd-cfDNA analysis for kidney transplant recipients conducted to date, involving:
- 25 international and US sites
- 367 biopsy-matched samples from adult kidney transplant recipients
- 125 histology-confirmed rejections in an indication biopsy cohort
