What Major Drivers Are Impacting The Companion Diagnostics Market?

The rising availability of targeted therapies is projected to fuel the expansion of the companion diagnostics market. This medical approach specifically identifies and attacks distinct features of cancer cells to impede their development and dissemination. While circulating throughout the body, these medications achieve a more precise impact compared to chemotherapy, often resulting in fewer side effects. Companion diagnostic testing, which relies on biological markers for targeted cancer treatments, is evolving into a vital component of individualized cancer care. For instance, in February 2024, according to the Personalised Medicine Coalition, a US-based hospital and health care organization, in 2023, the FDA approved 16 new personalized treatments for rare disease patients, up from six in 2022. Consequently, the increase in targeted therapies is a key driver for the companion diagnostics market’s growth.
