In addition, regular diagnostic testing allows veterinarians to establish what is considered normal for your individual pet. While each test comes with a normal range of scores, these ranges do not always take into account an animal's specific breed, size, age, or past health history. Your pet’s own baseline score when he or she is healthy is also an important factor to consider when determining whether your pet is sick.
For example, hematocrit is a red blood cell test used to detect anemia in animals. Imagine that your dog has consistent hematocrit scores year after year. Then, one year the results suddenly take a significant drop. This change could signal a problem even if the most recent score is still within the test’s normal range.
Diagnostic testing becomes more important as dogs and cats age. Many pets 7 years old and older receive diagnostic testing annually, both to establish a baseline and to help identify potential health problems. In addition to the regular round of diagnostic testing, these pets may benefit from additional testing or from having certain tests performed more frequently than once a year. Your veterinarian will be able to customize a program suited to your pet’s age, breed, and overall health status.
Most veterinarians recommend several tests to help establish the health of your pet. A complete blood count looks at red blood cells, white blood cells and platelets, and can help identify signs of infection or anemia. A biochemical profile looks at how effectively organs, such as the kidneys and the pancreas, may be functioning. This profile also helps veterinarians examine factors such as blood sugar (glucose) level and the amount of calcium and phosphorous in the body. This information can be invaluable, as high levels of glucose can indicate diabetes, while high calcium levels have been linked to certain types of cancer. Veterinarians also conduct an electrolyte panel, which shows sodium, potassium and chloride levels in your pet's blood. Electrolytes are a key part of nerve and muscle function. Taken together, these tests can enable early disease detection, which can make it easier for your veterinarian to treat a hidden medical problem.
Even your pet’s waste offers valuable information. One crucial test is the urinalysis, which looks at your pet’s urine. A urinalysis is often necessary to help interpret blood test results, and it can help identify possible health problems. Fecal exams, which analyze your pet’s stool, should be performed at least once a year to help your veterinarian identify whether your dog or cat is harboring parasites that could affect your pet—as well as other family members. Depending on where you live — and where your pets play — more frequent testing for parasites may be warranted.
Other tests relate to your pet’s lifestyle. For example, it’s especially important for cats that go outdoors to be tested for feline leukemia virus and feline immunodeficiency virus.
Senior pets may need more specific testing. As pets age, they are more at risk for developing certain illnesses and health complications, like thyroid disease or kidney problems. Diagnostic testing provides a way to identify these potential concerns early. Your veterinarian may suggest some of the following tests for senior pets:
After all these diagnostic tests are completed, your veterinarian hopes that nothing is found. Why? Because that means your pet is healthy. And that’s the most vital test for cats and dogs to pass, year after year.
