New Research Shows the PrecivityAD2™ Blood Test Has High Accuracy Compared to Amyloid PET Scans in Individuals with Cognitive Impairment
The AUC-ROC for the PrecivityAD2 test output, the Amyloid Probability Score 2 (APS2), was 0.94, yielding 88% agreement with brain amyloid status based on a single cut-off value.
- The AUC-ROC for the PrecivityAD2 test output, the Amyloid Probability Score 2 (APS2), was 0.94, yielding 88% agreement with brain amyloid status based on a single cut-off value.
- The APS2 result was the most robust method among the individual plasma amyloid and tau analytes measured to identify disease.
- In the published study, the PrecivityAD2 blood test was clinically validated in 583 individuals with cognitive impairment across two independent cohorts.
- C₂N is working toward obtaining the requisite certification that will permit the PrecivityAD2 test to be available in New York in the near future.
