IgE testing identifies immediate allergic reactions, such as hives, sneezing, and anaphylaxis, caused by foods or environmental allergens. IgG4 testing, on the other hand, focuses on chronic food sensitivities or long-term exposure to certain antigens, which can cause conditions like irritable bowel syndrome (IBS) or gastrointestinal discomfort. Together, IgE and IgG4 testing provide a comprehensive picture of both your immediate allergies and long-term sensitivities, helping you manage symptoms more effectively and improve your overall well-being.

Allerim Health uses advanced liquid allergen technology, which preserves the natural structure of allergens, ensuring more accurate detection of allergen-specific IgE and IgG4 antibodies. Our tests have a lower detection threshold, allowing for earlier and more precise identification of even minimal immune responses. Unlike conventional tests, our technology reduces false positives and offers testing for over 500 allergens, providing a more comprehensive and reliable diagnostic tool.

Yes, IgG4 has a dual role in the immune system. Elevated IgG4 levels can indicate a chronic immune response to certain foods, suggesting a food sensitivity. At the same time, IgG4 is also associated with immune tolerance, especially in cases of immunotherapy, where high IgG4 levels reflect the body’s adaptation to allergens. This means IgG4 can help identify foods that may be causing long-term symptoms and also show when the body is becoming tolerant to certain exposures.

At Allerim Health, we personalize our testing based on a detailed intake of your dietary habits, symptoms, and medical history. This helps us select the most relevant allergens and food antigens for testing. By focusing on your unique history of allergic reactions and sensitivities, we can provide more accurate and actionable results, guiding you toward better health management.

After testing, we provide you with comprehensive results that highlight your specific allergies and sensitivities. From there, we collaborate with healthcare providers to create personalized dietary plans and explore options like food desensitization or probiotics to help manage or reduce symptoms. Our precision approach ensures that you not only receive an accurate diagnosis but also actionable steps for long-term allergy and immune health improvement.
