Cats + Diagnosis

  • Pandora syndrome affects multiple organ systems, including the urinary tract. The term is often used synonymously with Feline Idiopathic Cystitis (FIC), but FIC is only one component of Pandora syndrome. It is believed to be related to chronic stress. This article discusses causes, signs, diagnosis, treatment, and prognosis for cats with this condition.

  • Pre-surgical testing is the best way to minimize anesthetic risks and ensure good surgical outcomes. Pre-anesthetic testing consists of, at minimum, a full physical examination and may include complete blood count (CBC), serum biochemistry, urinalysis, radiographs, EKG, or more advanced testing. The results of pre-surgical testing are used to formulate the safest anesthetic plan for your pet.

  • Preparing your pet for a blood test helps to ensure that the results are as accurate and reliable as possible. Preparation for routine and special blood tests is slightly different. Your veterinarian will give you specific instructions before your appointment. It is important that you follow these instructions exactly to ensure accurate test results.

  • The American Animal Hospital Association and American Veterinary Medical Association have established guidelines to standardize preventive health care for cats, helping them to live longer, healthier lives. This handout provides an overview of the recommendations within these guidelines and why they are so important.

  • X-ray images are produced by directing X-rays through a part of the body towards an absorptive surface such as an X-ray film or electronic sensor. The image is produced by the differing energy absorption of various parts of the body. Bones are the most absorptive and leave a white image on the screen, whereas soft tissue absorbs varying degrees of energy depending on the density, producing shades of gray on the image. Air on an X-ray is black. X-rays are a common diagnostic tool used for many purposes.

  • Adrenocorticotropic hormone (ACTH) is produced in the brain and regulates the production of cortisol. When blood cortisol levels are low, it is secreted to stimulate more production, and when blood cortisol levels are high (like from an adrenal tumor), ACTH production is suppressed. ACTH testing alone cannot be used to diagnose Cushing's disease but can help determine what type of Cushing's disease the patient has.

  • Serum biochemistry measures the amount of enzymes, proteins, sugar, electrolytes, minerals, and hormones found in the liquid portion of the blood. Testing for these substances provides information about the body’s organs and tissues, as well as the metabolic state of the animal. This article provides general information on the most routinely measured factors in serum and common reasons for abnormal readings.

  • Electrolytes are the salts and metallic components that are dissolved within the blood serum (serum is the liquid portion of blood). The electrolytes of greatest clinical importance are sodium, potassium, chloride, bicarbonate, phosphorus, and calcium. It is important to detect changes in electrolyte concentrations so that these changes can be treated before the situation becomes severe or life-threatening.

  • Serum iron tests are indicated when the results from a complete blood count (CBC) indicate that your pet is anemic (meaning they have decreased red blood cell numbers and/or decreased hemoglobin) and that the red blood cells are microcytic (smaller than usual) and hypochromic (contain less hemoglobin than usual). Tests to assess iron deficiency require a single blood sample that is sent to a veterinary referral laboratory.

  • Serum contains many proteins that perform diverse functions, which include providing cellular nutrition, defending against infections, playing a role in inflammation, and acting as hormones or enzymes. Protein electrophoresis is a specialized test that analyzes specific groups of proteins in the blood serum and measures how much of each group of protein is present. The results of the analysis help diagnose specific diseases, such as infection and some types of cancer.
