Glossary

Glossary of Allergy Terms.


Allergen:
A foreign substance that gives rise to allergies by starting an immune response

Allergic rhinitis (seasonal):
Inflammation of the mucous membranes of the nose due to an allergic response; seasonal allergic rhinitis occurs in response to allergens present during part of the year; seasonal allergic rhinitis is also known as hay fever
Return to top

Allergy skin test:
The scratching or injection of a small quantity of allergen into the skin to produce visible redness and bump; used to identify allergens responsible for allergies
Return to top

Allergy:
A sensitivity to an otherwise harmless substance.
Return to top

Antibody:
Any of a number of proteins produced in response to an antigen that acts specifically against that antigen in an immune response
Return to top

Antihistamine:
A drug that inhibits the action of histamine; a drug that reduces hay fever symptoms, i.e., sneezing, runny nose, and itchy, watery eyes
Return to top

Cilia:
Hairlike projections in the mucous membrane of the nose that help nasal passages remain clear
Return to top

Corticosteroid:
Anti-inflammatory drug that reduces airway inflammation causing a reduction in nasal swelling and swelling of bronchial tubes; can cause weight gain and increased appetite
Return to top

Decongestant:
A drug that narrows blood vessels and clears nasal congestion; can cause elevation in blood pressure and nervousness
Return to top

Desensitization:
Administration of low but increasing doses of an allergen in order to decrease the allergic response to that allergen; also known as hyposensitization or immunotherapy
Return to top

Eczema:
Dry, itchy, noncontagious skin rash frequently caused by allergies.
Return to top

Elimination diet:
A diet from which common allergenic foods and those suspected of causing allergic symptoms have been temporarily eliminated.
Return to top

Epinephrine:
Adrenaline; a hormone secreted by the adrenal gland that stimulates heart rate and causes constriction of blood vessels, thus increasing blood pressure
Return to top

Hay fever:
An allergic condition characterized by inflammation of the mucous membranes of the eyes, nose, throat, and respiratory tract. Accompanied by sneezing, runny nose, watery eyes, and itching of the eyes, nose, and throat.
Return to top

Heredity:
Transfer of genetic qualities or traits from parents to children
Return to top

Histamine:
One of a number of body substances released by mast cells that cause allergic symptoms.
Return to top

Hypoallergenic:
Refers to products formulated to contain the fewest possible allergens. Such products are not necessarily safe for everyone.
Return to top

Immune system:
The body's defense system, composed of specialized cells, organs, and body fluids. It has the ability to locate, neutralize, metabolize, and eliminate unwanted or foreign substances.
Return to top

Immunoglobulin E (IgE):
One of a class of proteins manufactured by specialized immune cells that help to deactivate foreign material or invading organisms that cause disease
Return to top

Immunology:
The science and study of the nature and causation of protection against infections and allergenic substances.
Return to top

Immunotherapy:
The process by which an allergy patient is exposed, usually by injection, to gradually increasing amounts of an allergen for the purpose of decreasing sensitivity to the allergen; mechanism of action is not clear
Return to top

Inflammation:
The reaction of tissues to injury from trauma, infection, or irritating substances. Affected tissue can be swollen, hot, red, and/or tender. Oxygen availability may be reduced in these tissues.
Return to top

Ingestant allergens:
Substances that are swallowed to which a person is sensitive, eg, foods, beverages, or drugs.
Return to top

Inhalant allergens:
Any airborne substance small enough to be inhaled into the lungs, eg, pollen, dust, mold, and animal danders.
Return to top

Injectant allergens:
Substances injected into the body to which a person is allergic. Usually drugs and insect venom.
Return to top

Mast cells:
Cells involved in the immune response and that play a role in allergy by releasing substances that lead to symptoms such as runny nose and mucus production. Mast cells contain packets of chemicals (eg, histamine) responsible for the symptoms of allergy.
Return to top

ImmuneTech Allergy Test:
The fastest, most cost effective and “patient-friendly” way to determine precisely what you and your family are allergic to.
Return to top

Mucous membranes:
Moist tissues forming the lining of body cavities that have an external opening, such as the respiratory, digestive, and urinary tracts.
Return to top

Optimal dose:
Dose that gives the most complete relief for the longest period of time, with the least number of side effects.
Return to top

Overload:
The overpowering of the immune system due either to massive, concurrent exposure or to low-level continuous exposure caused by many stresses, including allergens.
Return to top

Patch/scratch tests:
A form of skin testing in which suspected allergens are applied to the skin, covered, and observed for several days to see if a reaction occurs. This is often used in identifying the possible causes of allergic contact dermatitis. Should not be attempted at home.
Return to top

Pharmacology:
The science and action of medicines, their nature, preparation, administration and effects
Return to top

Pollen:
Tiny male fertilizing agent of flowering plants, trees, grasses and weeds. Airborne pollen is a major allergen responsible for hay fever.
Return to top

Postnasal drip:
The leakage of nasal fluids and mucus down into the back of the throat.
Return to top

Radioallergosorbent (RAST) test:
Allergen testing carried out in a test tube. A patient blood sample is mixed with a test allergen. A radioactive antibody capable of detecting human antibodies is added. A positive test identifies an allergen capable of causing an allergic response.
Return to top

Sensitivity:
An adaptive state in which a person develops a group of adverse symptoms to the environment, either internal or external.
Return to top

Sensitization:
Exposure to a foreign substance resulting in an allergic response
Return to top

Symptoms:
A recognizable change in a person's physical or mental state that is a departure from normal function, sensation, or appearance, and which may indicate a disorder or disease.
Return to top

Syndrome:
A group of traits or concurrent symptoms; indicates the presence and nature of a condition or disease
Return to top

Target organ:
The particular organ or system in an individual that will be affected most often by allergic reactions to varying substances.
Return to top

Tolerance:
The capacity of the body to withstand repeated exposures without symptoms.
Return to top

Toxicity:
A poisonous, irritating, or injurious effect resulting when a person ingests or produces a substance in excess of his or her tolerance threshold.
Return to top

Urticaria:
Hives or welts that could be caused by allergies.
