Companion diagnostics refer to medical tests that aid physicians in identifying the most suitable treatment strategy. They are crafted to detect specific biomarkers present in a patient's tissue or blood sample, indicating whether the patient is likely to respond positively to a particular drug or therapeutic approach. Additionally, they delve into the intricate biological profile and mechanism of action (MOA) of patients, assisting healthcare professionals in comprehending potential medication side effects. The widespread application of companion diagnostics is evident in personalized medicine, where it takes into account the distinct characteristics of each patient, such as their genetic composition, to determine the optimal treatment course. Beyond this, there is a growing use of companion diagnostics for examining specific genetic mutations in cancer patients or identifying biomarkers in those with hepatitis C.
