Final answer:
Serum dehydrogenase (SDH) is an enzyme measured in both small and large animals to assess liver health and cellular damage.
Step-by-step explanation:
Serum dehydrogenase (SDH) is an enzyme that is measured in both small animals and large animals to assess cellular damage and liver health. SDH is often part of a biochemical profile used to evaluate the liver, as it is released into the bloodstream when liver cells are damaged. This enzyme can be an important marker for veterinarians in diagnosing and monitoring various conditions related to the liver or muscle damage in animals.
