I’ve been reading this excellent book “The Age of Scientific Wellness: Why the Future of Medicine Is Personalized, Predictive, Data-Rich, and in Your Hands.”; the chapter on cancer talks about something called “Galleri test” – this test sounds like a very innovative approach for cancer screening, and can potentially disrupt PCR-based tests:
I talked to someone who works in the diagnostics space and he said: Galleri test is based on detection of cfDNA, a method which is already being used in monitoring of organ transplants. While the technology is very innovative, the relative lack of specificity in predicting organ involved limits it’s widespread use. The cost is also a concern (at least in India). It needs more refinement and cost rationalization for widespread adoption.
