About Precision Diagnostics
Precision Diagnostics is a trailblazer and leader in clinical pharmacogenomics (PGx) and nutrigenomics (NGx), driving the real-world adoption of precision medicine and precision nutrition across Asia Pacific, located in the heart of Kuala Lumpur, Malaysia. We are proud to be awarded as the First Clinical-Recommended Genome-Wide Pharmacogenomics. We are honored by our distinguished strategic collaborations with world-leading institutions and authorities, including National Institutes of Health (Ministry of Health Malaysia), University of Oxford’s Serenox (United Kingdom), University of Liverpool (funded by the National Health Service [NHS] Race and Health Observatory, Chief Investigator NHS England’s Chair of Pharmacogenetics Professor Sir Munir Pirmohamed), National University of Singapore, Commonwealth Medical Association, and are also invited by UNESCO Chair in Bioethics. We strictly adhere to leading guidelines from reputable organisations and global standards including the United States Food and Drug Administration (FDA), the Singapore Health Sciences Authority (HSA), the Clinical Pharmacogenetics Implementation Consortium (CPIC), the Dutch Pharmacogenetics Working Group (DPWG), and the International Warfarin Pharmacogenetics Consortium (IWPC).
We go beyond testing. The PRECISE Ecosystem drives full-scale Clinical Pharmacogenomics Implementation—bridging R&D and academic education to clinical application, both locally and internationally—through strategic collaborations with leading universities, hospitals, clinics, pharmacies, professional societies, and policymakers. In parallel, the PRECISE Infrastructure delivers seamless adoption in real-world clinical practice by providing clinical-accredited and clinician-friendly reports, clinical decision support systems (CDSS), dedicated clinical support teams, and practical education. Together, these integrated solutions make pharmacogenomics adoption fast, simple and effective
As an ISO 15189 certified laboratory, Precision Diagnostics voluntarily sets higher standards and has consistently achieved good grades in multiple College of American Pathologists (CAP) External Quality Assessments (EQA), ensuring adherence to the highest global standards and best practices. We transform Research-Use-Only (RUO) tests into validated Laboratory-Developed Tests (LDTs), bringing research into clinical application. Our commitment is to elevate personalised medicine through advanced diagnostics, ensuring that our clients receive the most precise and impactful healthcare solutions available.
Our flagship clinical services—PRECISE Pharmacogenomics, PRECISE Onco+, PRECISE CardioMetabolic+, and PRECISE Nutrigenomics—empower safer, more effective, cost-efficient, and highly personalized treatment decisions across 20+ therapeutic areas, including oncology, cardiology, psychiatry, neurology, pain management and metabolic care. Our Complete Pharmacogenomics Solutions span the full spectrum—from single-drug testing to comprehensive genome-wide and whole-genome sequencing, and from rapid point-of-care diagnostics to the most cutting-edge long-read technologies—empowering both reactive and pre-emptive care.
Trusted by leading hospitals, physicians, and healthcare institutions, Precision Diagnostics is the genomic engine behind patient-first care. We don’t just deliver test results—we deliver clinical evidence, clinical actionable, and real clinical impact in personalized care. Advancing Tomorrow’s Cure!
