Immuno globulin E
Immuno globulin E Immuno globulin E is the antibody produced in excess in allergic patients. IgE can be measured in a blood sample to determine if a person is allergic. Allergic people usually have high levels of IgE.
RELATED TERMS--------------------------------------
Antibody
An infection-fighting protein molecule in blood or secretory fluids that tags, neutralizes, and helps destroy pathogenic microorganisms (eg, bacteria, viruses) or toxins. Antibodies, known generally as immunoglobulins, are made and secreted by B-lymphocytes in response to stimulation by antigens. Each specific antibody binds only to the specific antigen that stimulated its production.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
SIMILAR TERMS--------------------------------------
Immune
Resistant to a particular disease.
Immune adherence
The adherence of particulate antigen coated with C3b to tissue having cells with C3b receptors.
Immune complex
Antigen bound to antibody.
Immune modulators
Substances that control the expression of the immune response.
Immune response (Ir) gene
A gene controlling an immune response to a particular antigen; most genes of this type are in the MHC (major histocompatibility complex), and the term is rarely used to describe other types of Ir genes outside the MHC.
Immune System
The body's natural defense system which produces antibodies to fight against foreign substances such as bacteria, viruses, toxins, and cancers.
Immunity
When a body's immune system helps fend off disease.
Immunization
Natural immunity provided by antibodies or induced immunity via inoculations.
Immuno-Augmentative Clinic
The Immuno-Augmentative Clinic is a hospital in Freeport, Freeport, Bahamas.
Immunoassay
Detection and assay of substances by serological (immunological) methods; in most applications the substance in question serves as antigen, both in antibody production and in measurement of antibody by the test substance.
Immunofluorescence
Technique allowing the visualisation of a specific protein in cells or tissue sections (prepared from a biopsy) by binding a specific antibody conjugated to a fluorescent substrate.
Immunogen
A substance capable of inducing an immune response (as well as reacting with the products of an immune response). Compare with antigen.
Immunoglobulin
A serum protein involved in immunity. An antibody.
Immunoglobulin (Ig)
A general term for all antibody molecules. Each Ig unit is made up of two heavy chains and two light chains and has two antigen- binding sites.
Immunoglobulin E (IgE)
A type of antibody, formed to protect the body from infection, which attaches to mast cells in the respiratory and intestinal tracts and may cause allergic rhinitis, asthma, or eczema.
Immunoglobulins
Antibodies or proteins found in blood and tissue fluids produced by cells of the immune system to bind to substances in the body that are recognized as foreign antigens. Immunoglobulins sometimes bind to antigens that are not necessarily a threat to health and provoke an allergic reaction.
Immunohistochemical staining
A laboratory process of detecting an organism in tissues with antibodies. These antibodies are labeled with a compound that is seen as a colored deposit when viewed microscopically. In general, mesotheliomas require immunohistochemical confirmation before legal measures are initiated.
Immunology
The study of the body's natural defense system.
Immunosuppresive medications
Medications that suppress the body's immune system, used to minimize rejection of transplanted organs.
Immunosuppression
The artificial suppression of the immune response, usually through drugs, so that the body will not reject a transplanted organ or tissue. Drugs commonly used to suppress the immune system after transplant include prednisone, azathioprine (Imuran), mycophenolate mofetil (CellCept), and cyclosporine (Neoral).
Immunotherapy
Stimulating the body's natural defense system to attack and destroy cancers.
Immutable
Long-lasting and unchangeable.

Immuno globulin E
Inflammation
A reaction to an injury to the body - by infection, chemicals or physical agents. The symptoms can be - depending on the location of the injury- redness, swelling, heat and pain. The purpose of the inflammation is to dilute and destroy the agent causing the inflammation. To do this, the immune system starts a cascade of actions that causes active cells to gather at the affected location. It is these cells and fluids that cause the redness, swelling, heat and pain.
Intracutan test
Intracutan tests are used to diagnose allergies. A small amount of allergen extract is injected under the skin on your arm. If the area becomes itchy, reddish and swelling you may have an allergy.
Implantation
The process by which an embryo becomes attached to the inside of the uterus (7-14 days in humans).
In utero
Latin: literally, "in the uterus."
Informed consent
A process in which a patient gives written consent (agreement) to undergo a medical procedure after having been provided with information about the nature of the procedure, risks, potential benefits, alternatives, and so on by his or her doctor.
