Analysis on allergies
Analysis on allergies is the best way to indicate allergen and the appointment of the necessary treatment. The main thing is to make it timely
To find out what is the analysis of blood to allergies, first we will understand what is an allergy. This word of Greek origin and translates as «Other feeling», «Other perception».
This is «Failure» In the work of immunity leading to excessive sensitivity to the impact of certain agents. For people inclined to the emergence of the sensitization reaction, anyone surrounding its substance can become an irritant.
For example, dust tick, pollen, wool or saliva of animals and birds, medical preparations, food, fertilizers and t.NS. This disease may arise spontaneously and just as spontaneously disappear. And can exhaust a person for a long time with its manifestations and periods of exacerbation. The manifestations of the disease can be very diverse: from the cold, turning in the throat and skin problems, to anaphylactic shock.
The priority goal of treating this disease is the detection of a provocation factor, for the most quickly neutralization of its action. This is difficult, since allergies for some one irritant to meet is extremely rare.
Preferably, cross or polyvalent reaction occurs when the body responds immediately to the impact of several agents. In order to reveal these agents and cure allergies to hand over the specific tests of Invitro.
What kind of tests are needed?
In order to examine the patient objectively and comprehensively, it is necessary to pass the following blood tests:
- General blood analysis;
- Determining the level of immunoglobulin E;
- Detection in the blood of specific antibodies LGG and LGE;
- Skin tests.
The general study of blood is carried out to identify the number of specific cells of eosinophils, which determine the presence of body sensitization.
After general, it is necessary to hand over the following analysis for allergies – the overall level of immunoglobulins E. Increased level of these proteins also reflects the presence of an immune response in the body.
And if the LGE level is normal, but the suspicion remains, then the patient is prescribed the following study – the definition of the presence in the blood of specific IgG antibodies (IgG4) and IgE. These antibodies characterize the reaction to certain substances in the body.
For example, the reactions in which immunoglobulin e acts in the body immediately, as soon as a foreign agent gets into it. And the reactions under which the effect of immunoglobulin G is observed: the body responds after a few hours, and sometimes days after entering a foreign substance.
What allergies can be revealed using analyzes?
In order to perform blood test on allergies in the patient take venous blood. Then the tests are performed, under which the patient’s blood contact is investigated with all allergenic allergens.
Tests, combined into the so-called panels, including the following groups:
- Helminth;
- Vegetable;
- Household;
- Professional;
- Grocery;
- Animal origin;
- Provoked by mold mushrooms.
Each panel includes from several units to several tens of substances. The doctor prescribes an analysis on a panel, depending on probable contacts with substances in the patient before the appearance of symptoms of the disease.
The following analysis of allergies, performed by Invitro – skin tests. They are performed as follows: a drop of a solution of one or another allergen is applied on the inside of the hand and a puncture or a small scratch is made through it.
If blister or redness is formed on the site of the puncture, the test is considered positive, t.E. On this reagent causes allergies in the body.
Skin tests are contraindicated to children under five, pregnant and elderly people, for two reasons:
- A few days before the test, it is necessary to stop the reception of antihistamine preparations, and this is not possible in each case;
- When performing the test, a certain substance falls into the blood, that is, if the patient occurs, anaphylactic shock may develop the reaction to a particular reagent.
Where it is better to be examined?
To date, in our country there is a huge number of private laboratory centers, where you can pass any analyzes for allergies.
In addition, there are specialized centers and practically in every district hospital there is a specialist who will appoint the necessary surveys and tell me where to perform them.
Follow your health and refer to experts on time!
