Companion Diagnostics Are Becoming A Standard Drug Development Step
Companion diagnostics, once a niche regulatory requirement for a handful of targeted oncology drugs, are becoming a standard element of precision oncology drug development, with regulators increasingly expecting a validated molecular test alongside any new targeted therapy submission. That shift ties diagnostic revenue directly to pharmaceutical pipeline timelines rather than to independent laboratory demand, converting molecular diagnostics companies into genuine development partners rather than downstream test suppliers. Companies with deep companion diagnostic development relationships are winning platform selection decisions years before a therapy reaches commercial launch, locking in testing volume that independent laboratories cannot easily displace.
