P4 Diagnostix operates as a network of testing and diagnostic facilities integrated into a single lab services organization, designed to streamline access to testing and related resources for healthcare clients. The network brings together leading labs and pathology practices—including Theranostix, Long Island Pathology, Platinum Pathology, Metamark Laboratories and P4 Clinical. Its model emphasizes connectivity and consultative partnerships, with its diagnostic and office-workflow integration supported by a partnership with VitalAxis, a healthcare informatics provider. Headquartered in Beltsville, Maryland, the company operates within the hospitals and health care industry, serving physician-owned labs and healthcare providers that rely on integrated diagnostic services. A notable development is a 2022 collaboration with PierianDx to support physician-owned labs, reflecting the network’s continued expansion of diagnostic capabilities.
