Profile bio

About Jay Chang, Md (Ob/Gyn)

Scaling Patient Care. I started as a fire fighter helping hundreds of people. Then I helped tens of thousands as an OBGYN. Now I am helping millions at BillionToOne. BillionToOne's quantitative counting templates (QCTs) are as transformative as polymerase chain reaction (PCR). PCR has always been good at telling you if there are needles in a haystack. QCTs unlock the potential to tell you how many needles are in the haystack. This is not a small step forward. This is the giant leap. My favorite part about QCTs is the fact it is a simple solution to complicated problem. Anyone can come up with complicated solutions to complicated problems. But it takes true genius to find a simple solution. A solution that leaves everyone wondering, "Why didn't I think of that!" That's the true brilliance behind QCTs.QCTs are succeeding where real-time PCR, digital PCR, and digital droplet PCR failed. Fetal screening using maternal blood is finally possible. If QCTs were a microscope, everything that came before is a magnifying glass. Imagine the waves QCTs will make in oncology. Everything including cancer screening, diagnostics, recurrence monitoring, residual disease, surgery, drug selection/resistance monitoring, prognosis, etc. will change forever.
