Definition: What are companion diagnostics?

Companion diagnostics refer to medical tests or assays that are specifically designed to identify biomarkers or genetic mutations in patients. These biomarkers or mutations are closely associated with a particular disease or condition, and the results of the companion diagnostic test can help healthcare professionals make informed decisions about the most appropriate treatment options for individual patients.

Companion diagnostics are often used in the field of personalized medicine, where treatments are tailored to the specific characteristics of each patient. By identifying biomarkers or genetic mutations that are indicative of a particular disease, companion diagnostics can help determine whether a patient is likely to respond to a specific therapy or drug.

These tests are typically performed alongside the development of new drugs or therapies, as they can provide valuable information about the efficacy and safety of the treatment. Companion diagnostics can also be used to monitor the progress of a patient’s treatment and assess their response to therapy over time.

Overall, companion diagnostics play a crucial role in improving patient outcomes by enabling personalized treatment approaches and ensuring that patients receive the most effective and appropriate therapies for their specific conditions.
