TRI-DELTA DIAGNOSTICS, Inc. provides diagnostic test kits that detect acute phase proteins in blood or milk of animals at an early stage of disease. These proteins are an indication of the presence of an inflammatory process, often a bacterial or viral infection, and can be detected before the animal shows physical signs of ill health. Acute phase proteins are routinely used in human diagnostic medicine.

Acute phase proteins cannot be detected in normal healthy animals. However, research has shown that if animals are exposed to a bacterium or virus or put in a stressful environment, such as poor living or transport conditions, the animal produces large amounts of these proteins as a natural defense mechanism. Pharmaceutical companies, universities and academic establishments and commercial food producers use these kits routinely to monitor animal health.
