Symptoms of Food and Respiratory Allergies

Allergic reactions can affect different parts of the body, and symptoms often vary in intensity from person to person. Common signs that you may be experiencing a food or respiratory allergy include:

• Respiratory symptoms: sneezing, nasal congestion, runny nose, coughing, wheezing, or difficulty breathing.
• Skin reactions: rashes, redness, itching, hives, or eczema flare-ups.
• Digestive issues: bloating, stomach cramps, nausea, diarrhea, or other gastrointestinal discomfort.
• Other general symptoms: watery or itchy eyes, fatigue, and in severe cases, anaphylactic reactions

These symptoms can appear suddenly after exposure to an allergen, or develop gradually over time. In many cases, people experience discomfort without clearly understanding what is causing it. Reactions may occur after eating certain foods like gluten, dairy, nuts, or seafood, or after exposure to airborne allergens such as pollen, dust, or pet dander. Identifying the underlying triggers is essential for managing these symptoms effectively.

Causes of Food and Respiratory Allergies

Food and respiratory allergies occur when the immune system mistakenly identifies harmless substances as threats. In response, the body produces allergen-specific Immunoglobulin E (IgE) antibodies. When these antibodies bind to an allergen, they trigger the release of histamine and other chemicals that lead to allergic symptoms.

Several factors can contribute to the development of allergies:

• Genetic predisposition: individuals with a family history of allergies are more likely to develop allergic reactions.
• Environmental exposure: contact with allergens such as pollen, dust, mold, animal dander, or certain foods can trigger immune responses.
• Immune system sensitivity: variations in how the immune system reacts can make some people more prone to allergic reactions.

Allergens may be found in common foods like gluten, dairy, nuts, and seafood, or in environmental sources like pollen, dust mites, and airborne particles. Because immune responses vary over time and between individuals, pinpointing the exact cause without testing can be difficult, leaving many people guessing or relying on elimination diets.

Benefits of the Food and Respiratory Allergy Test

The EasyDNA Food and Respiratory Allergy Test offers a scientifically validated, laboratory-based approach to identifying allergens and understanding your body’s immune response. Unlike temporary blood or skin tests, this test evaluates your inherited allergy potential, providing a more complete picture of your susceptibility.

Key benefits include:

• Identifies specific allergens: reveals sensitivity to foods like gluten, dairy, nuts, seafood, and airborne triggers such as pollen.
• Personalized, easy-to-read report: shows the level of immune response for each allergen, helping you understand your risk.
• Actionable insights: allows you to make informed adjustments to your diet, environment, and lifestyle.
• Convenient home testing: simple, safe sample collection kit sent to your home, no clinic visit required.
• Long-term value: results provide lifelong insights because your DNA does not change, making it useful for proactive health management.
• Peace of mind: replaces uncertainty and guesswork with clear, scientifically backed information.

This test is especially valuable for those with family history of allergies, seasonal symptoms, or dietary issues, giving you the confidence to make informed decisions for yourself and your family while improving long-term comfort and wellbeing.

What the Food and Respiratory Allergies Test Tells You

The Food and Respiratory Allergies Test from EasyDNA is a reliable way to identify allergens that may be affecting your health. Once your sample reaches our laboratory, it is tested against a comprehensive panel of food and inhalant allergens. The test measures your immune system’s production of allergen-specific Immunoglobulin E (sIgE) antibodies, which are responsible for immediate allergic reactions such as sneezing, itching, or digestive discomfort.

Your detailed report includes:

• Levels of sIgE response to each tested allergen.
• A complete list of food and respiratory allergens included in the test.
• A descriptive interpretation of your immune reactivity for each allergen.
• A professional explanation of what your results mean and how they may relate to possible symptoms.
• These insights allow you to pinpoint which allergens are most relevant to your lifestyle, providing a practical foundation for managing allergic reactions and improving your overall health.

Convenient Home Sample Collection of the Food and Respiratory Allergy Test

The Food and Respiratory Allergies Test is designed for at-home use, making testing simple and stress-free. Your kit includes everything needed to collect a few drops of capillary blood on Whatman paper.

• No special preparation is required.
• Avoid antihistamines or allergy medications for 3 o 10 days before testing, depending on the type of medication. Always consult your physician before stopping any prescribed treatment.
• Once your sample is returned, results are typically available within 10 to 15 working days, giving you fast, actionable insights into your allergies.

How to Interpret Your Food and Respiratory Allergies Test Results

Your results provide an objective measure of allergic sensitisation to each tested allergen. The Food and Respiratory Allergies Test classifies your immune response into classes 0 to 6, where:

• Class 0 – negligible IgE levels.
• Classes 1–2 – low to moderate response.
• Classes 3–4 – moderate to strong response.
• Classes 5–6 – very high levels, indicating a strong immune reaction.

The test uses advanced immunoassay technology, with analytical sensitivity ranging from 83% to 100% depending on the allergen. IgE levels can fluctuate over time, influenced by exposure and immune activity, so your results should be interpreted as part of a broader clinical picture.

Understanding your Food and Respiratory Allergies Test results allows you to make informed lifestyle and dietary adjustments, discuss findings with healthcare professionals, and take proactive steps to manage allergies effectively, enhancing your quality of life.

The Science Behind The Food and Respiratory Allergy Test

Allergic reactions occur when the immune system mistakenly identifies harmless substances, such as foods or airborne particles, as threats. In response, it produces Immunoglobulin E (IgE) antibodies. When these antibodies bind to an allergen, they trigger the release of histamine and other inflammatory chemicals responsible for common allergy symptoms.

The EasyDNA Food & Respiratory Allergy Test analyses allergen-specific IgE antibodies associated with allergic immune responses. Using advanced immunoassay technology, the test measures both the presence and concentration of IgE antibodies across a wide range of food and respiratory allergens in a single laboratory analysis.

Results are reported in classes from 0 to 6, where Class 0 indicates negligible IgE levels and Class 6 reflects a very strong immune response. This structured classification provides a clear, objective indication of allergy-related sensitisation and its intensity.

The test offers high analytical performance, with sensitivity typically ranging from 83% to 100%, depending on the allergen assessed. As IgE levels may vary over time due to exposure and immune activity, results should be interpreted as part of a broader clinical picture.

Overall, the Food & Respiratory Allergy Test provides a reliable and evidence-based foundation for clinical discussion, long-term allergy management, and targeted lifestyle adjustments aimed at improving quality of life.

Allergy Reactions vs Intolerances

Although often used interchangeably, allergies and intolerances differ in how the body responds. Allergies involve the immune system and can lead to immediate reactions such as swelling, respiratory distress, or skin flare-ups shortly after exposure.

Intolerances typically do not involve IgE antibodies and are usually less severe. Symptoms may include bloating, abdominal discomfort, fatigue, or headaches, and can occur hours or days after consuming the trigger substance.

Unlike allergies, intolerances may change over time as dietary habits and lifestyle factors evolve. Individuals primarily interested in intolerance-related reactions may prefer a dedicated Food Intolerance Test.

Living with allergies can be frustrating but understanding what is behind them makes all the difference. The Food & Respiratory Allergies Test offers a scientifically validated way to uncover your specific triggers. It focuses specifically on immune-mediated (IgE) allergic responses that provides scientifically validated assessments of your immune system. This test is an essential toolkit that helps you to manage long-term allergy symptoms.
