What is wellness testing?
Wellness testing is the term given to a group of tests that is performed specifically to detect signs of early disease in a pet that is apparently healthy. Wellness testing is a simple and effective way of monitoring your pet’s health. Early detection and correction of medical problems help to ensure that your pet will have a long, healthy, and active life. Why do wellness testing? Pets cannot tell you how they are feeling, and as a result disease may be present before you are aware of it. If a disease or condition can be detected before a pet shows signs of illness, we can often take steps to manage or correct the problem before irreparable damage is done.
When is wellness testing done? Wellness testing is usually done once yearly, and many pet owners combine wellness testing with their annual visit to the veterinarian for their pet’s physical examination, vaccination, or heartworm testing. Your veterinarian may recommend more frequent testing depending on your pet’s specific health concerns. Monitoring your pet’s health status on a regular basis makes it easier for the veterinarian to detect minor changes that signal the onset of disease.
What is involved in wellness testing? There are four main categories of wellness testing for your pet:
Complete Blood Count (CBC) Chemistry Profile Thyroid hormone testing (T4) Urinalysis
Complete Blood Count – This simple blood test analyses the cellular components in the bloodstream. These include red blood cells, which carry oxygen to the tissues, white blood cells, which fight infection and respond to inflammation, and platelets, which help the blood to clot. The CBC provides details about the number, size, and shape of the various cells types, and identifies the presence of any abnormal cells.
Chemistry Profile – This is a series of tests performed on serum, which is a component of blood. These tests provide information about how well the various organs of the body are working, and help to detect the presence of some metabolic diseases. There are tests to assess the liver, kidneys, and pancreas, tests to identify the presence of diabetes, and so on. If minor abnormalities are found on the biochemistry profile, the veterinarian may simply request that you repeat the tests at a later time; depending on the abnormality, this may be in a few days, a few weeks, or a few months. In some cases, a more extensive diagnostic workup may be recommended, including an expanded chemistry profile, or special tests and/or imaging (x-rays, ultrasound).
Thyroid testing (T4) – The thyroid gland is like a “thermostat”, and it “sets” the metabolic rate of the whole body. The most common thyroid disease in the dog is called hypothyroidism, which occurs when the thyroid does not produce adequate amounts of thyroid hormone. The most common thyroid disease in the cat is called hyperthyroidism, which occurs when the thyroid produces too much thyroid hormone.
Urinalysis – Urinalysis involves an analysis of the chemical components in urine, as well as a microscopic examination of the cells and solid material present in urine. Urinalysis provides information about how well the kidneys are working, identifies the presence of inflammation or infection, and may detect the presence of underlying metabolic disease such as diabetes. Urinalysis is necessary for a complete assessment of the urinary system. Ideally it should be performed as part of wellness testing, and is especially important whenever there is concern about kidney function or underlying metabolic disease.
