Laboratory diagnostics of allergies: modern methods for detecting allergens
Allergy is not just an unpleasant discomfort, but a serious disruption of the immune system, which can significantly worsen the quality of life. Frequent runny nose, itchy throat, watery eyes or even attacks of suffocation can be a sign of an allergic reaction. However, without an accurate determination of the causes, it is impossible to avoid the manifestations of allergies. Laboratory diagnostics allows you to accurately determine which substances cause the body's reaction, helping doctors develop an effective treatment and prevention plan.
What is laboratory allergy diagnosis and why is it important?
Allergic reactions occur due to the increased sensitivity of the immune system to certain substances - allergens. They can be of different origins: pollen, food, household, medicinal or insect. In some cases, allergies can manifest themselves weakly, for example, in the form of sneezing or skin rashes, while in more serious situations it can lead to anaphylactic shock, which is life-threatening.
Laboratory allergy testing allows not only to determine the presence of an allergy, but also to identify specific allergens to which the body reacts. Unlike skin tests, laboratory tests do not cause discomfort or the risk of aggravating allergic reactions, which makes them a safe diagnostic method.
Basic methods for diagnosing allergies
| Diagnostic method | What determines | Advantages |
| Blood test for immunoglobulin E (IgE) levels | Detects general allergic sensitivity | Safe, possible even during an allergy exacerbation |
| Specific IgE tests | Identify specific allergens (pollen, foods, animal dander) | High accuracy, no risk of anaphylactic reaction |
| Allergy test (molecular diagnostics) | Detects specific allergen proteins | Helps identify risks of severe reactions and cross-allergies |
| Leukocyte activation test | Analyzes the reaction of leukocytes to allergens | Suitable for patients with chronic allergic conditions |
| Basophil activation test | Examines the functioning of basophils in the blood upon contact with allergens | Helps assess the effectiveness of treatment |
In addition to laboratory tests, doctors may recommend skin tests, but they have more contraindications and can cause discomfort.
When is it necessary to undergo laboratory diagnostics of allergies?
Laboratory tests for allergies should be taken if the following symptoms appear:
- chronic runny nose, nasal congestion
- sneezing attacks, itchy nose or throat
- tearing, redness of the eyes
- frequent skin rashes, hives
- attacks of shortness of breath, wheezing, coughing
- digestive disorders (abdominal pain, nausea, diarrhea) after eating certain foods
It is especially important to conduct laboratory diagnostics of allergies in children, because timely detection of allergens will help avoid complications in the future.
How to properly prepare for allergy testing
To ensure that the test results are as accurate as possible, it is necessary to follow the basic preparation rules.
- Do not take antihistamines for 3-7 days before testing (as agreed with your doctor)
- Avoid physical exertion and stress the day before the analysis
- Do not consume potentially allergenic foods (nuts, citrus fruits, chocolate) the day before testing.
- Take a fasting blood test, especially if the study is comprehensive.
- Do not smoke or drink alcohol before taking the test.
Following these recommendations will allow you to obtain accurate results and correctly identify the source of the allergic reaction.
