Precision Epigenomics presents Episeek MCED test results at ASCO
August 2025—Precision Epigenomics presented validation data for its flagship multicancer early detection (MCED) test, Episeek, at the 2025 ASCO annual meeting in Chicago, May 30–June 3. The data demonstrated that the blood-based test is capable of identifying more than 60 cancer types with a 99.5 percent specificity rate and a turnaround time of two to three days. The test was validated on 281 cancer-positive plasma samples across all four stages and 201 samples from healthy people over 40 years old. It showed a 45 percent sensitivity for stage I/II cancers and a 74 percent sensitivity for stage IV cancers, with positive and negative predictive values of 64.9 percent and 99.5 percent, respectively.
