Quad Five produces the highest quality animal blood and serum biologicals available for use in human diagnostic testing in the world.

Superior and Sustainable

Healthy donor animals are key to producing superior biological products for our global partners.

Located in central Montana, Quad Five harvests blood from donor sheep, horses, bovine, and goats, which live in a clean, healthy, controlled environment on our 9,000 acre ranch. Our top priority is to produce the most consistent and traceable blood fractions in the market.

By monitoring every aspect of animal health, facility technicians ensure product quality and performance consistency.

Exceptional service, competitive pricing, and rapid fulfillment are hallmarks of the Quad Five customer experience.
