Quad Five is a leading producer of medical-grade animal blood and serum products for use by medical centers, laboratories, universities, and pharmaceutical companies across the globe. We are the only biological producer in the U.S. to harvest 100% of our blood from donor animals, not animals bound for slaughter.
Blood, as a biological fluid, can be adversely affected by many different parameters, including age, genetics, diet, health, and environment of the source animal. Quad Five has developed a proprietary donor animal program to control these issues, ensuring the highest quality and consistency. Our commitment to providing top medical-grade products is in lockstep with our commitment to the quality treatment and care of our donor animals. At Quad Five, integrity and sustainability go hand-in-hand.
