Allergy tests

From the common point of view, the identification of the causes of allergic diseases is necessarily connected with the staging of Allergy testing. The first question that a patient visits a doctor, it is often: "How many samples you I will put?" Often the number of samples depends on the credibility of the doctor in the eyes of the patient.
Indeed, in many countries employ hundreds of different tests. What is the real value of various Allergy testing in specific diagnosis of allergic diseases?
In our opinion, Allergy tests are one of the biological methods in complex diagnostics of allergic diseases. In any case, allergic diseases no test may be "the only superatom", with the help of which it is possible to make a diagnosis. However, it should be acknowledged that different allergic tests in complex with other methods play an important role in specific diagnostics of many allergic diseases. Allergic skin tests with proper evaluation (results should not be overestimated and underestimated!) play an important role in practical Allergology.
The first important question: what tests should be applied? Second: in all cases of using skin tests or only selectively, according to testimony? In some countries, doctors-allergists at specific diagnosis of allergic diseases used by several hundreds of different tests, and then on their basis for a diagnosis. There is no doubt that this formulation unscientific tests and diagnostics of allergic diseases is not helping. Another extreme: for a specific diagnosis apply 2-3 tests (usually do doctors, poorly familiar with the problem of Allergy).
The challenge skin tests must flow from the data carefully collected allergological anamnesis and complete clinical examination of the patient. In practical Allergology, as in other clinical disciplines, the results of clinical and biological research methods should be subject to a comprehensive analysis and evaluation. The lack of a thorough analysis of the results of allergic skin samples often leads to errors in diagnosis. Many companies for specific diagnosis of allergies to various chemical substances are used mixed allergens, including several chemical substances and related different chemical composition. Analysis of the results of such tests is difficult, therefore, staging tests with mixed allergens cannot be justified and recommended. In the formulation of skin tests, you must perform the following:
1. A good analysis of the collected allergological anamnesis. Allergy tests should be put only on the testimony allergological anamnesis; they must confirm or reject the suspicions of the physician regarding the "responsibility" of an allergen. For example, the occurrence of allergic reactions when in contact with animals (at the use of any products and so on).
2. Analysis of the circumstances under which regularly appear allergic symptoms: seasonality, professional and other factors In such cases, skin tests with different allergens necessary and valuable.
When questionable data coupled allergic history, the doctor may use an allergic tests to identify the cause of the disease.
Contact dermatitis to identify specific allergen skin tests are indispensable: on the results you can rely on. In allergic rinosinusopatiyah, bronchial asthma, hives and Quincke's edema not always using skin tests, you can identify all of the specific allergens. When drug Allergy using skin tests specific allergen can be detected in a very small percentage of cases.
Some allergists attach great importance to the results of skin tests in bacterial and fungal allergens, while they account for allergic skin reaction delayed type. We believe that the results of these tests can be relied on only in cases dramatically positive reactions with the formation of intensive infiltration and skin necrosis at the injection allergen. But these strongly positive, allergic skin reactions, delayed type must be carefully weighed against data allergological anamnesis and clinic of the disease.
