Can Sequencing replace traditional diagnostics in India? Traditional diagnostics are slow. Culture and antibiotic resistance tests take days or even weeks to deliver results. This can be detrimental for patients suffering from sepsis or fever of unknown origin. Meanwhile, sequencing technology has evolved to the point where it can identify both the pathogen and its antibiotic resistance in a single test. Technical challenges include cost, sample prep complexity, and the need for skilled workforce in labs. Business challenges include competing for distribution with established brands like Lal path, MedGenome. On the flip side, sequencing offers massive sample multiplexing, lower turnaround time, and better diagnostic accuracy. I believe there’s potential to build a 100cr revenue business just for infectious disease testing within 3-5 yrs. The same sequencing platform can also be expanded to other areas like liquid biopsy testing, creating further opportunities.
