Since the launch of P4 Diagnostix in 2006, the company has consistently worked to provide enhanced testing and positive outcomes for patients and practitioners.

P4 is the result of the combination of several laboratories, including Theranostix, Platinum Pathology, Metamark Laboratories Inc., P4 Clinical (previously known as Manhattan Labs) and Long Island Pathology, as well as partnerships with P4 Physicians, MetaMark Genetics, Vital Axis and Vital Logistics.

Together, we launched an industry leader in diagnostic pathology offering best-in-class testing services and healthcare informatics.
