The science behind the certainty
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 lung to determine whether or not you may be experiencing active rejection. It may also indicate other types of lung 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 lung. You can measure new results against this baseline.
- Following your levels in the future reveals your new organ’s health
If a Prospera result is above 1.0%
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 transplanted organ is stable.
