YD Bio and EG BioMed Expand U.S. Access to OkaiDx™, a cfDNA‑Methylation Blood Test for Post‑Treatment Breast Cancer Monitoring

Taipei, Taiwan, Nov. 05, 2025 (GLOBE NEWSWIRE) -- YD Bio Limited (“YD Bio” or the “Company”) (NasdaqGM: YDES), a biotechnology company advancing DNA methylation-based cancer detection technology and ophthalmologic innovations, today announced its support for the global commercialization of OkaiDx™, a research‑use‑only (RUO) blood test for post‑treatment breast cancer monitoring now available through the Company’s affiliate EG Biomed US Inc. (“EG BioMed”)’s CLIA/CAP‑certified laboratory in the United States. YD Bio’s role is to support commercialization efforts for OkaiDx™ under the authorization granted to the Company, working alongside EG BioMed to make the assay accessible to research laboratories, academic groups and industry partners conducting surveillance and translational studies. OkaiDx™ was developed through international scientific collaboration and uses cfDNA methylation profiling to generate molecular surveillance information for research settings. The test has been reported in peer‑reviewed journals such as Clinical Epigenetics and Biomolecules, and presented at major oncology conferences. EG BioMed’s CLIA and CAP accreditation enables U.S. testing and reporting of RUO assays in an accredited laboratory environment, while YD Bio’s support complements EG BioMed’s laboratory capabilities by helping coordinate commercialization, researcher engagement and sample logistics for study use. YD Bio’s involvement follows its ongoing partnership activities with EG BioMed to expand U.S. laboratory access for cutting‑edge molecular assays, said Dr. Ethan Shen, Founder, Chairman and Chief Executive Officer of YD Bio Limited. “Independent validation already reported performance metrics of 95.1% accuracy, 89.4% sensitivity and 96.5% specificity,” he said. YD Bio is helping to commercialize OkaiDx™ for research applications. As of present day, the test is for research use only, and has not been cleared or approved by the U.S. Food and Drug Administration, and is not intended to diagnose, treat, cure or prevent any disease. The Company expects OkaiDx™ to provide a research‑grade tool that may enable investigators to study post‑treatment monitoring approaches and to generate additional evidence that could inform future clinical development.
