What is wellness testing?

Wellness testing is a program of check-ups and blood tests designed to detect early or hidden disease in pets that appear to be healthy.

Why should I do wellness testing?

Cats are very good at masking illness, and disease may be present even in cats that appear to be healthy. If a disease or condition can be detected before a cat shows signs of illness, you can often take steps to manage or correct the problem before permanent damage occurs.

When is wellness testing done?

Wellness testing should be done regularly, and many pet owners combine wellness testing with their cat’s annual visit to their veterinarian for physical examination, vaccination, and parasite prevention.

"Your veterinarian may recommend more frequent testing, depending on your cat's age or specific health concerns."

Your veterinarian may recommend more frequent testing, depending on your cat's age or specific health concerns. Monitoring your cat’s health on a regular basis makes it easier for your veterinarian to detect minor changes that signal the onset of disease.

What is involved in wellness testing?

There are three main categories of wellness testing for young to middle-aged cats: complete blood count (CBC), biochemistry profile, and urinalysis. Your veterinarian will advise you on how extensive the testing should be for your cat. In younger cats without noticeable health complaints, relatively simple testing may be adequate. In middle-aged cats, more comprehensive testing may be beneficial.

Complete Blood Count (CBC)

This test gives information about the different cell types in the blood. 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 cell types and identifies the presence of any abnormal cells. It is a routine test used in all stages of health and illness and can indicate the presence of many forms of disease (for more information, see handout “Complete Blood Count”).

Biochemistry Profile

This panel of tests provides information about the organs and tissues of the body and helps to detect diabetes, kidney disease, liver disease, endocrine disease, and other disorders (for more information, see handout “Serum Biochemistry”). If minor abnormalities are found on the biochemistry profile, your veterinarian may suggest that the tests be repeated in a few days, weeks, or months. If the abnormalities are more serious, then a more extensive diagnostic workup may be recommended, including an expanded biochemistry profile and/or imaging tests such as X-rays (radiographs) or ultrasound.


Urinalysis is a routine test that reports the microscopic and chemical properties of a pet’s urine (for more information, see handout “Urinalysis”). The test provides information about how well the kidneys are working and identifies inflammation and infection in the urinary system. It can also help to detect diabetes and can be useful in the diagnosis of cancer in the urinary system. Urinalysis is part of any comprehensive assessment of the kidneys and urinary system and should be included in routine wellness testing.

This three-part illustration explains the common screening tests: complete blood test, serum biochemistry, and urinalysis. Part 1: A complete blood test (CBC) analyzes the cellular components of the blood. Illustration shows red blood cells, white blood cells, and platelet cells. Part 2: Serum biochemistry is the chemical analysis of the liquid component of blood that remains after the cells and clotting factors are removed. Illustration shows a test tube with a small amount of red at the bottom (blood cells), and a pale-yellow liquid (serum) at the top. Part 3: Urinalysis includes a dipstick test of the chemical properties of the urine. Illustration shows a cup of urine and some small, paper dipsticks with stripes of various colors that will test for various chemicals in the urine.

Wellness testing is a simple and effective way of monitoring your cat's health.  Early detection allows for correction or management of medical problems before they become serious. This helps to ensure that your cat will live a long, healthy, and active life.
