Symptoms can range from mild discomfort to serious health threats, such as anaphylactic shock. To determine exactly which substances cause an allergic reaction, allergen testing is used.<\/p>\n<p data-start=\"498\" data-end=\"766\">Early diagnosis allows not only to identify allergy triggers, but also to develop an effective treatment and prevention plan. This is especially important for people who experience seasonal allergies, allergic reactions to foods, medications, dust, or insect bites.<\/p>\n<h2 data-start=\"768\" data-end=\"817\"><strong data-start=\"771\" data-end=\"815\">When to get an allergen test<\/strong><\/h2>\n<p data-start=\"819\" data-end=\"874\">A doctor may order testing for the following symptoms:<\/p>\n<ul data-start=\"876\" data-end=\"1214\">\n<li data-start=\"876\" data-end=\"929\">constant runny nose, nasal congestion, frequent sneezing<\/li>\n<li data-start=\"930\" data-end=\"975\">watery, itchy, or red eyes<\/li>\n<li data-start=\"976\" data-end=\"1016\">rash, itching, or dry skin<\/li>\n<li data-start=\"1017\" data-end=\"1056\">attacks of suffocation, cough, bronchospasms<\/li>\n<li data-start=\"1057\" data-end=\"1088\">swelling of the lips, tongue, face<\/li>\n<li data-start=\"1089\" data-end=\"1165\">nausea, abdominal pain, indigestion after eating certain foods<\/li>\n<li data-start=\"1166\" data-end=\"1214\">chronic fatigue, headache, dizziness<\/li>\n<\/ul>\n<h2 data-start=\"1216\" data-end=\"1262\"><strong data-start=\"1219\" data-end=\"1260\">Basic allergen testing methods<\/strong><\/h2>\n<p data-start=\"1264\" data-end=\"1375\">Depending on the suspected allergen and the patient&#039;s general condition, several <a href=\"https:\/\/medilab.km.ua\/en\/laboratory-diagnostics-of-allergies-modern-methods-of-detecting-allergens\/\">diagnostic methods<\/a>.<\/p>\n<h3 data-start=\"1377\" data-end=\"1399\"><strong data-start=\"1381\" data-end=\"1397\">Skin tests<\/strong><\/h3>\n<p data-start=\"1400\" data-end=\"1656\">This is one of the most accurate and fastest methods of determining allergies. A small amount of allergen is applied to the patient&#039;s skin and a micro-scratcher or injection is made. After 15-20 minutes, the reaction is assessed - redness or swelling indicates an allergic response.<\/p>\n<p data-start=\"1658\" data-end=\"1804\">The advantage of the method is that it provides quick results, but it is not suitable for people with active allergies or those taking antihistamines.<\/p>\n<h3 data-start=\"1806\" data-end=\"1835\"><a href=\"https:\/\/medilab.km.ua\/en\/price\/?3325_search_1=IgE&amp;3325_device=laptop&amp;3325_orderby=relevance&amp;3325_paged=1&amp;3325_filtered=true\"><strong data-start=\"1810\" data-end=\"1833\">Blood test for IgE<\/strong><\/a><\/h3>\n<p data-start=\"1836\" data-end=\"2089\">Determining the level of specific immunoglobulin E class in the blood helps to diagnose sensitivity to various allergens. The method is suitable for people who cannot undergo skin tests, for example, due to severe allergic reactions or chronic skin diseases.<\/p>\n<p data-start=\"2091\" data-end=\"2213\">Preparation for the analysis includes donating blood on an empty stomach, avoiding stress and physical exertion on the eve of testing.<\/p>\n<h3 data-start=\"2215\" data-end=\"2243\"><img decoding=\"async\" class=\"alignnone size-full wp-image-8438\" src=\"https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic.jpg\" alt=\"Laboratory blood test for allergens\" width=\"1200\" height=\"800\" srcset=\"https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic.jpg 1200w, https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic-150x100.jpg 150w, https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic-600x400.jpg 600w, https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic-300x200.jpg 300w, https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic-1024x683.jpg 1024w, https:\/\/medilab.km.ua\/wp-content\/uploads\/2025\/03\/healthcare-concept-clinic-768x512.jpg 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/h3>\n<h3 data-start=\"2215\" data-end=\"2243\"><strong data-start=\"2219\" data-end=\"2241\">Provocative tests<\/strong><\/h3>\n<p data-start=\"2244\" data-end=\"2516\">This method is used in medical settings to confirm an allergic reaction.
