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.
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.
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).
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.
