Cats + Diagnosis

  • Testing for Increased Thirst and Urination

    Various conditions can cause increased thirst (polydipsia) and urination (polyuria). Based on your pet's history and a thorough physical examination, your veterinarian will recommend diagnostic testing to determine the cause. This handout describes several tests that can be performed along with the conditions the results from these tests may indicate.

  • Testing for Jaundice

    Jaundice is caused by the build-up of bilirubin in the tissues due to high blood levels of bilirubin (hyperbilirubinemia) in the blood. Hyperbilirubinemia occurs either due to increased red blood cell destruction (hemolysis), or an inability of the liver to process or excrete bilirubin normally. CBC, biochemistry panel, and urinalysis are tests used to further define the cause of jaundice. Further diagnostics that may be needed and include ultrasound, X-ray, FNA, liver biopsy and/or bacterial culture from fluid found in or around the liver. More specific tests for infectious diseases include FeLV, feline coronavirus, and fungal testing.

  • Testing for Kidney Disease

    Tests to diagnose kidney disease include complete blood count (CBC), serum biochemistry, and urinalysis. Further diagnostic tests may be recommended based on the results of these initial screening tests. The additional tests help to identify the cause and severity of kidney disease, which will help determine the best treatment plan for your pet.

  • Testing for Lameness

    Lameness in your pet can be due to many possible causes. Examination may help determine the cause, but further testing may include radiographs, blood tests, or joint aspirations to help accurately determine the cause. Treatment and prognosis for the lameness will depend on the underlying cause.

  • Testing for Liver Disease

    Initial screening tests for liver disease include a complete blood count (CBC), biochemistry panel, and urinalysis. Bile acid testing can be used to detect problems in liver function. More advanced diagnostics to determine the cause of liver disease include abdominal ultrasound, fine needle aspiration of the liver, or liver biopsy. Testing for various infectious diseases, including leptospirosis, may also be indicated.

  • Testing for Low Blood Sugar

    Hypoglycemia can be caused by many different things including liver failure, sepsis, Addison's disease, and overdose of insulin in the treatment of diabetes mellitus. A tumor of the pancreas called an insulinoma can also cause low blood glucose due to excessive production of insulin. After detecting hypoglycemia on a blood sample, determining the cause includes a full history, physical exam, CBC, biochemistry profile, and urinalysis. More advanced testing such as imaging, biopsy, or ACTH stimulation testing may be recommended.

  • Testing for Pallor

    In pets, pallor is usually detected as a loss of color from the gums and inner eyelids and can be a sign of anemia or poor circulation. A pet’s history of illness and a complete physical examination are important in determining the cause of the pallor. However, your veterinarian may also recommend doing screening tests such as a complete blood count, serum biochemistry and urinalysis. Additional tests may also be needed.

  • Testing for Pancreatic Disease

    The pancreas is an abdominal organ responsible for regulating blood glucose (endocrine function) and releasing enzymes that aid in digestion (exocrine function). Problems with the pancreas can cause a variety of conditions, discussed here. Clinical signs and tests are outlined.

  • Testing for Seizures

    Finding the cause of a pet's seizures can be difficult. Screening usually starts with a complete history and physical examination, followed by blood and urine tests to look for underlying diseases that can cause seizures. If the cause still cannot be identified, it is possible that they originate within the brain itself and further neurologic testing might be advised.

  • Testing for Sneezing and Nasal Discharge

    Sneezing and nasal discharge can occur for many different reasons, including infection, allergy, foreign body, and tumors. A thorough history and physical exam is the first step in diagnosing the cause of sneezing/nasal discharge. Initial screening tests are outlined, including CBC, biochemistry profile, urinalysis, and coagulation testing. Specific tests and more advanced diagnostics are also summarized.
