Economic Moat
Quest Diagnostics possesses a powerful economic moat driven by its massive scale, which creates significant cost advantages and operational efficiencies that smaller laboratories cannot match. Furthermore, its extensive network of patient service centers and deep integration into the electronic health record systems of major hospital networks create high switching costs for healthcare providers, solidifying its market leadership.
