What is involved in the allergy test?
Allergy test is used to diagnose food and environmental allergies. There are two types of allergic tests: leather or prick, test and blood test. A doctor or nurse should take these tests. Allergy is an immune system disorder that causes harmless substances to exaggerate.
The skin test is the most common of all methods of allergy testing. The patient fills in a questionnaire to help determine food, airy and contact allergies they have noticed. The questionnaire is usually relatively detailed and asks for the number of allergic reactions, intensity and frequency for the last 12 to 18 months. A list of specific allergens is identified for testing. These allergens are based on known mutual relations and similarities. For example, there is no need to test oranges and lemons because below the same family.
DEPSITIVE TESTING PRINGS may be on the forearm or back that ends in the number of allergens included in the allergy test. The skin surface is wiped with an alcohol solution. DoctrineR then takes a sterile needle and immerses it in the allergen. The skin is broken and the allergen is inserted into the body. This process is repeated for each allergen they test.
A map or grid is created to monitor the location that has been used for diagnostic purposes. The patient moves to the waiting room and is observed for ten to 15 minutes. During this period, medical staff monitors the patient, only in case there is an extreme allergic reaction. A sudden drop in blood pressure, the occurrence of hives or the development of anaphylactic shock are serious reactions and require immediate medical attention.
At the end of the waiting period, the doctor returns and compounted the map on the skin. If you have an allergy, Welt will appear where the allergen was introduced. The skin will be very itchy, red and sensitive to the touch.
The blood test is a much less common allergy test. It is more expensive and there are several questions about the validity of the results. INThis test is taken by several bottles of the patient's blood. Total levels of IgE or immunoglobulin E in the blood are tested to determine whether a person has an excessive immune system.
The problem with this test stems from the fact that no specific allergens are identified. The process simply verifies that the body has an excessively active immune system. Several diseases and syndromes can create the same effect in the body, but are not at all related to allergies.
If you are going to have an allergy test, buy an antihistamine in advance and have it prepared as soon as the test is terminated. Keep in mind that the body will continue to respond to the allergen for several days after the test.
