Companion Diagnostics Market: Industry Overview and Outlook

The global companion diagnostics market is experiencing robust growth, driven by the rising demand for personalized medicine, increasing prevalence of cancer and chronic diseases, and significant investments in targeted drug development. Companion diagnostics are specialized tests that identify patient subgroups likely to respond to specific therapies, enabling more precise, effective, and safer treatment regimens. The market is projected to grow from approximately ₹47,500 crore (USD 5.7 billion) in 2024 to ₹97,200 crore (USD 11.7 billion) by 2035, at a CAGR of 6.8%12. Some forecasts indicate even faster growth, with the market potentially reaching up to ₹1,32,600 crore (USD 16 billion) by 2030, depending on adoption rates and technological advancements3. Key trends include the integration of next-generation sequencing (NGS), liquid biopsy, and artificial intelligence (AI) in diagnostics, as well as regulatory encouragement from agencies like the FDA and EMA for co-development of drugs and companion diagnostics. The oncology segment, particularly lung and breast cancer, dominates the market, but applications are expanding into neurology, infectious diseases, and rare disorders43.
