Our vision is for DiaPharma to be the recognized source for hemostasis/special coagulation, cell death, and toxicology needs. We strive to dominate our markets by expanding our portfolio to ensure strength and stability.



The Diapharma Group, Inc. formed on January 1, 1997 from Pharmacia Hepar, Inc. in Franklin, Ohio, and began as the exclusive US and Canadian distributor of the Chromogenix substrates and assays.

Over a quarter-century ago, Chromogenix developed the first chromogenic substrate technology under the former name, Kabi Diagnostica. Kabi later merged with Pharmacia. Some of Diapharma’s current staff worked inside the Chromogenix department within Pharmacia’s heparin manufacturing plant.

In 1998, Diapharma moved to West Chester, Ohio, where it remains today. Over the years, Diapharma expanded its product line to include a variety of hemostasis, cell death, platelet function, ecotoxicology, assays, reagents, antibodies and instruments from superior manufacturers.



Diapharma’s major product areas include hemostasis, coagulation, anticoagulation, fibrinolysis, platelet function, cell death and toxicology. We sell individual bioreagents, controls, calibrators, substrates, deficient plasmas, antibodies as well as reagent complete chromogenic assays, clotting assays, ELISA test kits and instruments.
