  • This handout discusses arthroscopy, the insertion of a telescope-like camera into a joint. The joints commonly examined and treated using this technique, along with the benefits and risks of this procedure, are outlined.

  • The fastest way to examine large numbers of white blood cells is to look at a buffy coat smear. One of the most important cells to look for in a buffy coat is called a mast cell. Mast cells play an important role in allergies and related conditions. Mast cells can also form into tumors.

  • Cytology is a useful tool to often 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.

  • DNA is a large, complex molecule that carries the genetic information or “code” of an organism. All common forms of life carry a copy of their own genetic code in each of their cells, and each organism has a unique section of DNA that is just like a fingerprint. DNA-PCR is often used to detect the presence of infectious organisms.

  • 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.

  • 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.

  • 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.

  • 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 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.
