An allergy is an immune system malfunction that causes the body to have a hypersensitive reaction to a normally day-to-day substance. There are different types of allergy; nasal allergy, asthma allergy, food allergy, insect allergy, skin allergy but one may be reacting to only one type or some among all the allergies. One may be allergic to food, pollen, dust, insects, etc. So it is better to first test for the substance causing the allergy.
An allergy test of one form or another is often needed to determine which substance is causing the adverse reaction, if the problem seems to be originating from a food an allergy test may reveal that the individual is not allergic to the suspected food but to a certain element present in the food.
Although there are many allergy testing methods used to determine the presence of allergens, but the three most common allergy testing procedures are skin tests, elimination tests, and the radioallergosorbent test (RAST). It is seen that the accuracy of these tests varies widely and even the same test performed at different times may yield different results. It is also possible for a person to react to a substance during testing but no reaction in normal exposure.
Allergy skin testing is the most used of the three methods but it varies in methodology. With the scratch test a small amount of the suspected allergen is placed on the forearm or upper arm and then introduced under the surface by scratching or pricking. The skin is then observed for swelling or redness. Skin tests are useful in detecting respiratory allergies, penicillin allergy, insect allergies, and food based allergies.
Food allergies are also often investigated via an elimination diet. Suspect foods are removed from the diet for several weeks and then re-introduced one at a time with the person monitoring their reactions. The radioallergosorbent or RAST test is performed in a laboratory and tests for specific amounts of Immunoglobulin E (IgE) antibodies that will be present in the blood during a true allergic reaction.
