Allergy Skin Tests
Skin ARJ Tests
Test Arginer (also known as the test of skin tests for ARJ) is designed to test the reaction of the immune system to the person examined against the Targarat (allergen) is different (small proteins that excite immune reactions), in order to detect an arger response to a particular substance.
Skin sensitivity testing is carried out with the aim of diagnosing the allergic reactions or hypersensitivity of the person examined, especially for materials such as house dust, food molecules, pollen flowers, textile materials, paints, insect bites and animal fur.
During the examination of the Arger, the material (also called antigen-antigens) is injected with a very small amount under the skin or directly into the skin.
If the person being examined suffers from hypersensitivity to the injected substance, it is reflected in an immune reaction: secretion of substances such as histamine (histamine) and hyperactivity of the immune system cells, causing swelling, redness, itching or topical pain.
An immune reaction in the skin can be instantaneous (up to half an hour after injection) or late (about 24-48 hours after injection).
The screening of pregnant women is prohibited, except for special cases. The test is prohibited for young children (up to the age of 6-7 months), because there is no great importance for testing at these ages, where the organ the child’s immune system is mainly composed of antibodies taken from the mother during pregnancy or breastfeeding.
arcgi, Argitis (allergic rhinitis), fever of the Clay (hay fever), traumatic shock (anaphylactic shock), dermatitis (Dermatitis), dermatitis (contact Dermatitis).
How to prepare for the test
There is no reason to make special preparations. People who take medications of antihistamas or steroids are required to stop taking medication several days before the test (according to doctor’s instructions only), because they may hinder the reaction of the immune system to the test.
After the test
The person who performed the test must wait about 20-30 minutes outside the examination room, to see if there is an imme
When to perform the test
A test is carried out, often for persons who have suffered from aridity or transient hypersensitivity, seasonal or permanent, according to their medical record. When the outside is unknown.
Usually it is about people with chronic runny nose, nasal congestion, rashes, itching or swelling of the skin etc. In rare cases allergy appears as a symptom of a group that includes difficulty breathing, swelling of the face or neck and even fainting and loss of consciousness (also called talaq-anaphylaxis).
Method of conducting the examination
The Arger test is usually made on a wide area of skin such as back. The person being examined sits on the test chair. The Doctor sterilise the skin with a wet cloth, and divides the back area into parts, by drawing longitude and latitude with a test mark. In each box a drop is placed that contains another type of allergen, and then the skin is tingling by a precise needle, to enable the material to enter (with the name of the material injected into each part). A needle prick may cause pain slightly but it usually does not cause discomfort.
Sometimes less skin space is used, for example, in the forearm (if the test is for a certain number of exits).
diate reaction to the skin of a material.
In addition, this waiting time is set to make sure that a sharp group response does not appear, such as sudden drop in blood pressure, difficulty breathing and swelling of the facial area. If such a serious reaction occurs, the examined must be treated immediately with an adrenaline injection, but this is a rare case.
In rare cases the reaction of such a group occurs after a longer period of time, which must be reported immediately to the doctor and to receive treatment.
Analysis of results
The person who performed the Arger and skin sensitivity test returns to the clinic after approximately 48 hours, and the skin area on which the tests were performed is previewed.
The correct results of the Arger test:
No area appears in any swelling, redness or topical itching. The person examined did not show skin sensitivity to the material.
This does not preclude the presence of the Arger, but excludes the presence of a rabbit against the materials examined.
Improper results of the Arger test:
Swelling areas, redness or topical itching (usually appearing like a mosquito bite) have been observed. The person who performed the examination showed a topical dermal reaction to the substance in this area (mostly for the substance injected in this box), and apparently it is sensitive to the substance. You may receive an arger response to more than one article.
