Diagnosis

  • A fecal flotation is a screening test for internal parasites. It is performed by mixing a small sample of stool with a special solution that causes any parasite eggs to float to the surface of the solution. Young pets need multiple fecal flotations to screen for infection, while adults may only need a fecal screening once yearly unless they are at higher risk of infection.

  • A fecal occult blood test screens for the presence of hemoglobin (a component of red blood cells) in a fecal sample. Many conditions can cause blood to appear in the stool including intestinal ulceration, neoplasia, dental disease, and parasites.

  • FIP is one of the most challenging diseases to diagnose because feline coronaviruses are commonly found in the intestinal tract of many healthy cats. When this virus mutates or changes, clinical disease occurs. Unfortunately, routine blood testing for feline coronavirus is not clinically useful. Instead, testing is restricted to those cats in which a diagnosis of FIP is strongly suspected due to clinical signs and other supportive laboratory data. Histopathology remains the best way to diagnose FIP in the living cat.

  • Fine needle aspiration is a useful tool to collect samples for cytology and is often used to diagnose abnormal lumps on your pet's body as well as evaluation of fluid samples and tissue surfaces. It is relatively simple and inexpensive but can provide a lot of information. Depending on results, further tests may be indicated to best help your pet.

  • Flow cytometry is a laboratory technique that can be used for counting, examining, and sorting cells. A sample is passed through a light source and as the cells move through the path of the light source, they scatter the light in different ways.

  • Food allergies can be problematic for many cats, especially after years on the same diet. Clinical signs may manifest as gastrointestinal or skin problems. Animal proteins are the most common causes and strict avoidance is the best way to treat affected cats. An 8 to 12-week elimination diet trial on a special veterinary diet is the only definitive method to diagnose a food allergy and, in some cases, the veterinary diet may need to be continued long-term.

  • Food allergies can be problematic for many dogs, especially after years on the same diet. Clinical signs may manifest as gastrointestinal or skin problems. Some animal proteins are the most common causes and strict avoidance is the best way to treat affected dogs. An eight to twelve-week elimination diet trial on a special veterinary diet is the only definitive method to diagnose a food allergy and, in some cases, the veterinary diet may need to be continued long-term.

  • Gastrointestinal endoscopy uses a flexible tube with a camera or viewing port to inspect the esophagus, stomach, and first part of the small intestine, or the colon. The endoscope cannot reach all areas of the small intestine, so other tests may be needed to diagnose disease in these areas. 12–18 hours fasting and enemas are required prior to endoscopy depending on the area being studied.

  • Genetic (DNA) testing is readily available, whether you are using it for fun to find out what breeds your pet is made up of or if you are looking into possible medical conditions. DNA samples can be collected either from a cheek swab or a blood draw. Knowing which breeds your pet is made up of can help you and your veterinarian prevent or prepare for health issues in the future.
