ProsperaHeart

The science behind the certainty

 

A single, noninvasive dd-cfDNA blood test for heart transplant monitoring. Early insight into active rejection risk may change everything.

How does it work?

From a simple blood draw, Prospera measures the amount of donor DNA from your transplanted heart in your blood. This helps your care team assess all types of rejection more precisely than using the available standard assessment tools alone.

What do the Prospera results mean to me?

The Prospera result represents the percent of cell-free DNA in your blood that originates from the donated heart to determine whether or not you may be experiencing active rejection. It may also indicate other types of heart injury you are experiencing.

Like your other regular monitoring tests, Prospera is recommended for periodic use over time as directed by your doctor.

A way to track your cell-free DNA over time

  • Establishing a baseline tells you and your care team the “normal state” of your new heart. You can measure new results against this baseline.
  • Following your levels in the future reveals your new heart’s health

If a Prospera result is above 0.15%

This may mean that active rejection is occurring. Terms used to describe the various types of active rejection include:

  • Antibody-mediated rejection (AMR)
  • Acute cellular rejection (ACR)
  • Mixed rejection

To confirm a rejection and the type of rejection, you should consult with your doctor.

If a Prospera result is in the normal range

This may mean that your heart is stable.
