Addison's disease (the common name for hypoadrenocorticism) is caused by a decreased production of two hormones from the adrenal gland. These hormones are cortisol, a stress hormone, and aldosterone, a mineralocorticoid hormone that regulates the body's water balance through its effects on sodium and potassium.
Antibodies are specialized proteins, also called immunoglobulins that are primarily found in the bloodstream. They are produced by specialized white blood cells called plasma cells, a form of lymphocyte.
Arthroscopy is a minimally invasive therapy that is used to examine, diagnose, and treat diseases and conditions that affect joints. It requires a specialized piece of equipment called an arthroscope which will allow your veterinarian to look inside the joint using a small fiber optic camera that is hooked up to a monitor. It often requires general anesthesia; however, small incisions in the joint allow for a quicker recovery than traditional methods allow. The recovery time will depend on the extent of the injury, but compared to traditional surgery, recovery time is generally much shorter.
The bile acid test is a very useful test that helps to determine if the liver is working properly.
Bone marrow is the soft material found in the central core of many bones. Bone marrow is vitally important for the production of blood cells, specifically red blood cells, white blood cells, and platelets. Although many bones contain marrow, samples are collected from three main sites in cats and dogs: hip bone, top of thigh bone, or the forearm below the shoulder.
The first step in processing a blood sample is centrifugation. The blood is placed in a centrifuge, where it is spun in a small circle at high speed (much like a spinning ride at an amusement park).
Cerebrospinal fluid (or CSF) is formed within the brain, primarily at specialized sites called the choroid plexuses. CSF is found within the brain and in the space that surrounds both the brain and the spinal cord (this space is called the subarachnoid space).
Coagulation is the series of events that result in the formation of a clot. In the body, coagulation occurs after any injury to a blood vessel or tissue, in order to stop bleeding.
The Complete Blood Count, usually just called a CBC, is one of the most basic blood tests your veterinarian can request, and yet it is one of the most important tests for determining the health status of a pet. It includes a series of measurements that describe the quantity and quality of the cellular elements in the blood.
A Coombs' (or direct antiglobulin) test detects the presence of immunoglobulins (antibodies) on the surface of red blood cells. Immunoglobulins are proteins made by white blood cells (specifically plasma cells).
