Companion Diagnostics Market Size

The companion diagnostics market is a rapidly evolving segment within the healthcare industry, primarily driven by advancements in personalized medicine. Companion diagnostics (CDx) are tests or assays used to determine the suitability of a specific treatment for an individual patient. These diagnostic tools help healthcare providers identify patients who are most likely to benefit from a particular drug, thereby improving treatment efficacy and minimizing adverse effects. The growing prevalence of chronic diseases, particularly cancer, and the increasing adoption of targeted therapies are key factors fueling the demand for companion diagnostics worldwide.

In 2024, the global companion diagnostics market was valued at USD 8.34 billion. The market is projected to grow at a CAGR of 12.00% from 2025 to 2034, reaching an estimated USD 25.90 billion by the end of the forecast period. This substantial growth is attributed to the increasing use of precision medicine, rising awareness of personalized treatment approaches, and continuous technological advancements in the field of diagnostics. North America currently holds the largest market share, with Asia-Pacific emerging as a high-growth region due to increasing healthcare investments and government initiatives.
