A low level of Autoimmunity is beneficial, period. High autoimmunity means a person is allergic to himself or herself. The immune system begins to destroy the person it should protect. It is thought to cause arthritis, diabetes, and a host of other diseases.
A positive ANA test does not necessarily mean the patient has an autoimmune disease. An ANA test is not specific for autoimmunity, but is a sign of inflammation that is often specific to autoimmunity. Specific antibodies are usually tested for to determine if a patient has an autoimmune disease.
When the immune system mistakenly attacks a normal part of the body, this is known as autoimmunity. Autoimmunity that causes hypOthyroidism (low thyroid) is called Hashimoto's Thyroiditis. This condition can also cause hypERthyroidism as well. There are specific antibodies in patients with Hashimoto's. Autoimmunity that causes hypERthyroidism is usually a condition known as Graves' Disease. There are specific antibodies in patients with Graves' Disease.

CD4 T cells are a type of white blood or immune cell. Elevated levels suggest an immune response is underway. Most likely this is due to a mild infection but could also indicate autoimmunity (immune reaction against yourself).
the immune system
AIDS stands for Acquired Immune Deficiency. It is caused by a virus. It is not autoimmune. They are they exact opposite. In autoimmunity, the immune system is over active and mistakenly attacks the healthy self. In AIDS the immune system is extremely weakened and attacks next to nothing.
The immune system plays an important role in the body's defence mechanisms. It destroys and eliminates the pathogens that invade our bodies.
The medical term for the immune system failing to recognize its own body tissue and attacking its owner's body is autoimmunity. Common examples of autoimmune disorder are (a) Rheumatoid arthritis and (b) systemic lupus erythematosus ("lupus")
