Purposeto determine the correct therapeutic agent for an individual

A companion diagnostic (CDx)[1] is a diagnostic test used as a companion to a therapeutic drug to determine its applicability to a specific person.[2]

Companion diagnostics are co-developed with drugs to aid in selecting or excluding patient groups for treatment with that particular drug on the basis of their biological characteristics that determine responders and non-responders to the therapy.[3]

Companion diagnostics are developed based on companion biomarkers, biomarkers that prospectively help predict likely response or severe toxicity.[4]
