It is a blood test used to identify substances that trigger acute allergic reactions. A single blood draw can simultaneously measure IgE antibodies for up to 108 or 54 different allergens.<sup><a style=\"color: inherit;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/23484110\/\" target=\"_blank\" rel=\"noopener\">1<\/a><\/sup> <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IgE (Immunoglobulin E) is an antibody that mediates allergic reactions.

This is because the body&#8217;s immune response can change depending on age, environmental changes, and lifestyle habits. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Food allergies<\/strong> often disappear naturally as a child grows, even if they were positive during infancy. Egg and milk allergies are typical examples. Conversely, allergies to <strong>environmental allergens (house dust mites, pollen, etc.)<\/strong> tend to persist into adulthood. Furthermore, exposure to new environments (moving house, adopting a pet, etc.) may lead to new sensitizations to allergens that were not previously present.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Patients with <strong>chronic dermatitis<\/strong> should be particularly cautious. A weak skin barrier makes it easier for external antigens to enter the body through the skin, and this <strong>percutaneous sensitization<\/strong> can lead to new allergies that did not exist before. Therefore, if you suffer from chronic dermatitis and a long time has passed since your last test, it is highly recommended to consider retesting.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You may consider retesting in the following cases:<\/p>\n\n\n\n<ul class=\"wp-block-list has-custom-color-5-color has-text-color has-link-color wp-elements-41f7bb4539e12e7974eb5b55f6bf43c3\">\n<li>If more than 2\u20133 years have passed since the last test<\/li>\n\n\n\n<li>If your living environment has changed significantly, such as moving or adopting a pet<\/li>\n\n\n\n<li>If symptoms persist despite avoiding causative antigens based on previous results<\/li>\n\n\n\n<li>If chronic dermatitis has persisted for a long time and you wish to check for the possibility of new allergies caused by percutaneous sensitization<\/li>\n\n\n\n<li>If you want to check whether antigens that were positive during childhood are still problematic in adulthood<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 id=\"sec-5\" class=\"wp-block-heading\">5.

If the total IgE is high but no clear causative allergen is found, an additional 54-panel test may be recommended. The two tests cannot be done on the same day, requiring a separate visit, but if you visit within 10 days of the initial blood draw, the test can be performed without an additional draw.  <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-e2274529\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">If a food allergy is detected, must I stop eating that food?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>No. The MAST test shows the &#8220;possibility&#8221; of an immune response to a food; it does not necessarily mean it will cause symptoms. It is important to observe whether symptoms actually worsen when eating that food. Unconditional restriction is not recommended if it does not cause severe symptoms.   <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-cda88e2b\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can children be tested?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes, the test can be performed at any age as long as a blood draw is possible.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-f9ba8fe5\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can I be tested while taking antihistamines?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes, because the MAST test measures IgE antibodies in the blood, taking antihistamines does not affect the results. This differs from the skin prick test. <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-c7e34812\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Do test results change over time?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes, they can change. Food allergies (especially eggs and milk) often disappear naturally as a child grows, even if they were positive during infancy. Conversely, environmental allergens (house dust mites, pollen, etc.) tend to persist into adulthood, and new sensitizations can occur due to changes in the living environment. Consider retesting if it has been more than 2\u20133 years since your last result or if your environment has changed significantly.   <\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Tests Allergy Test (MAST) | Identifying the Causes of Atopic Dermatitis Flare-ups 1.
