While they\u2019re often discussed in the same space, they are fundamentally different in how they work, what they measure, and how reliable they are.<\/p>\n\n\n\n<p>So, what is bioresonance testing, how does it compare to IgG1-4 testing, and which approach should you trust?<\/p>\n\n\n\n<p>In this guide, we break down the differences, explain the science (and lack of it), and aim to help you make a more informed decision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Is IgG Testing?<\/strong><\/h2>\n\n\n\n<p>IgG testing is a laboratory-based blood test that measures levels of Immunoglobulin G(IgG) antibodies in response to specific foods.<\/p>\n\n\n\n<p>There are four subclasses of IgG antibodies: IgG1, IgG2, IgG3, and IgG4. YorkTest\u2019s <a href=\"https:\/\/www.yorktest.com\/us\/products\/premium-food-sensitivity\/\">Food Sensitivity Tests<\/a> analyse IgG 1\u20134 responses, providing a more comprehensive overview of how the immune system may be reacting to particular foods.<\/p>\n\n\n\n<p>These tests are typically carried out using established laboratory methods such as ELISA, ensuring consistency and measurable results.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What IgG Testing Can Show<\/h3>\n\n\n\n<p>IgG testing can help identify foods that your body may be producing an immune response to. For some people, this can be <em>incredibly <\/em>useful when exploring symptoms such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bloating<\/li>\n\n\n\n<li>Fatigue<\/li>\n\n\n\n<li>Headaches<\/li>\n\n\n\n<li>Digestive discomfort<\/li>\n<\/ul>\n\n\n\n<p>However, it\u2019s important to be clear that IgG testing is different from <a href=\"https:\/\/www.yorktest.com\/us\/products\/food-allergy-test\/\">allergy testing<\/a>. Immediate food allergies are typically associated with Immunoglobulin E (IgE) antibodies and can cause rapid reactions such as swelling, breathing difficulties, or anaphylaxis.<\/p>\n\n\n\n<p>IgG testing, including IgG 1\u20134 testing, measures a different type of immune response and is used in the context of food intolerances and sensitivities rather than diagnosing food allergies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Is Bioresonance Testing?<\/strong><\/h2>\n\n\n\n<p>Bioresonance testing is an alternative therapy that claims to detect \u201cenergy imbalances\u201d or \u201cstress responses\u201d in the body.<\/p>\n\n\n\n<p>It is often marketed as a way to identify:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Food sensitivities<\/li>\n\n\n\n<li>Allergies<\/li>\n\n\n\n<li>Toxins or intolerances<\/li>\n<\/ul>\n\n\n\n<p>Some providers offer bioresonance hair testing, where a hair sample is analysed rather than blood.

However, the interpretation of results is sometimes debated within the scientific community.<\/p>\n\n\n\n<p>Some experts argue that IgG reflects normal exposure to foods, rather than intolerance.
