Bringing dd-cfDNA testing to your own laboratory
One workflow. Reliable results.
dd-cfDNA Overview
Donor-derived cell-free DNA (dd-cfDNA) is used as a biomarker to assess organ health and rejection risk status
dd-cfDNA has a very short half life (30 minutes – 2 hours) and elevations can be detected almost immediately1
The use of dd-cfDNA as a tool for transplant monitoring is well established in over 60 publications across multiple transplant types
GraftAssure TM is a dd-cfDNA test that uses droplet digital PCR (dPCR) technology to measure the concentration of dd-cfDNA using 48 predefined SNPs with high minor allele population frequency. The kit enables the determination of both fractional (%) and absolute (copies/mL) concentration of dd-cfDNA for a comprehensive understanding of the amount of dd-cfDNA in the sample.
