Our Purpose
Our founder, Dr Rebecca Tay, lost her mother to colon cancer when she was a child. Just days after chemotherapy began, her mother passed away. That loss left her asking whether the same treatment could have been chosen more safely.
Years later, as a pharmacy and molecular medicine researcher, she saw how pharmacogenomics (PGx) can predict how a person's body responds to a drug. When her stepmother was diagnosed with stage 4 lung cancer, PGx-guided treatment and nutrigenomics (NGx) guided nutrition therapy supported her care. She was later confirmed cancer-free.
Genetic insight helps doctors choose the right drug and dose from the start, so avoidable harm and unnecessary tragedies can be prevented.
What our DNA tests do for you
PRECISE tests read your genes to show how you respond to medication and food, so care can be tailored to you instead of the average patient.
Safer prescribing
Identify genetic risks for adverse drug reactions before a medication is started.
More effective treatment
Match drug choice and dose to your genetic profile for better outcomes and less trial and error.
Wide medical coverage
More than 1,000 genes and 500 medications across 20+ therapeutic areas, including oncology, cardiology, psychiatry, neurology and pain management.
Personalised nutrition
Nutrigenomics shows how your body handles food, supporting diet plans and medical nutrition therapy built around you.
Test once, use for life
Choose reactive testing for a current treatment or pre-emptive testing to guide future prescriptions.
Clinician-ready reports
Clinically accredited reports with decision support, so doctors can act on results with confidence.
Our clinical services
Three tests, each covering a different part of personalised care.
