3. Lower risk of missing active rejection

In the event of a result with dd-cfDNA level <1%, Prospera is three times less likely to miss an active rejection† than first-generation dd-cfDNA.2,4

Comparison of Negative Predictive Values (NPV) from published validation studies

4. Ultra-sensitive for more accurate classification

When comparing published clinical validation studies, Prospera demonstrated better performance in correctly classifying patients with active rejection—including cell-mediated rejection.2,5

Other tests may incorrectly classify patients experiencing active rejection as normal (up to 1 out of 2 cases).5

Of 100 active rejection cases, the number of patients who would be missed, and told they are normal‡
