for Kidney Transplant Assessment

Covered by Medicare, Prospera™ is a transplant rejection assessment test that uses a simple blood draw to evaluate the risk of rejection of a transplanted kidney.

Through the use of advanced cell-free DNA technology, Prospera™ increases a provider’s ability to identify otherwise undetected rejection that might lead to kidney loss. Catching transplant rejection as soon as possible can help providers develop a treatment plan to best protect the donated kidney.

Setting a New Standard Through Research

Best-in-class care depends on best-in-class assessment

Prospera™ innovation is backed by deep data – reinforced by ongoing research efforts.

ProActive Registry Study: Completed Enrollment
  • Largest clinical utility study evaluating cell-free DNA; includes more than 3,000 kidney transplants studied for three years
  • Long-term assessment of high-risk recipients for up to 5 years post-transplantation
  • Personalized transplant management protocols using cell-free DNA data

PEDAL Study: Completed Enrollment
  • 500 kidney transplant patients from 20 major US centers
  • Evaluation of how quantifying the absolute concentration of background cell-free DNA (cfDNA) may allow for a more precise and confident assessment of allograft rejection — especially in identifying patients at-risk of false-negative interpretations
