Keeping a record of your companion’s immune system health, organ function values on a yearly basis enable much more thorough monitoring of your companion’s health. Trends and subtle changes can be detected that would otherwise go unnoticed. Basic annual wellness panels include a CBC, Chemistry panel, intestinal parasite screen, and heartworm test. A CBC or complete blood cell count quantifies the red blood cells, white blood cells and platelets, giving a wealth of information about your companion’s immune system health and function. The chemistry panel provides information about liver and kidney function, cholesterol level, gall bladder health, electrolyte balance and blood glucose level. The detail and features of the chemistry panel are individualized for each companion based on their health status. The intestinal parasite screen, also called a fecal test, monitors for intestinal parasites like worms and microorganisms that can compromise the health and well-being of your animal companion. Annual heartworm testing is advised by the American Heartworm Society.
