Wellness Testing in the Geriatric Pet

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.

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. Wellness testing is particularly important in the geriatric pet, since there is a greater chance that underlying disease may be present.

When is wellness testing done?
Wellness testing is usually done once yearly, your veterinarian may recommend more frequent testing depending of your cat’s age or 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 the geriatric pet: complete blood count (CBC), biochemistry profile, urinalysis, and (in cats) thyroid hormone testing. Within each category, the veterinarian will determine how extensive the testing should be. In younger pets without noticeable health complaints, relatively simple testing may be adequate. However, in the geriatric pet, more comprehensive testing is recommended.

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.

Biochemistry 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 biochemistry profile, or special tests and/or imaging (x-rays, ultrasound).

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. It should be performed routinely as part of wellness testing, and is particularly important in the geriatric pet because of the high rate of kidney disease in older pets.

The thyroid gland is like a “thermostat”, and it "sets" the metabolic rate of the whole body. Thyroid disease is common in the older geriatric cat, and cats that are more than eight years of age should be tested for thyroid function as part of routine wellness testing.

The most common thyroid disease in the cat is called hyperthyroidism, which develops when the thyroid gland produces excessive amounts of thyroid hormone. High levels of thyroid hormone cause a marked increase in the metabolic rate, which puts a strain on the heart and other organs. The typical signs of hyperthyroidism in the cat are unexplained weight loss despite as increased appetite, restlessness, increased thirst and urination, or vomiting and/or diarrhoea.

Summary
Wellness testing is a simple and effective way of monitoring your older pet's health. Early detection and correction of medical problems help to ensure that your pet will be healthy and active for as long as possible
