FAQ

Our test uses a small blood sample collected through a simple finger-prick kit provided. Once received, your sample is analyzed in our certified laboratory using the ELISA method.

This scientifically validated method measures IgG antibody levels in your blood against a wide range of foods. Elevated IgG levels may indicate that your body is reacting to certain foods, which could be contributing to symptoms like bloating, fatigue, or skin issues.

The results provide a personalized report, helping you identify potential food triggers and guiding your dietary choices.

The most accurate food intolerance tests are those that use blood samples to measure IgG 1, 2, 3, and 4 antibodies against a wide range of foods, typically using microarray technology. Among these, ELISA-based tests are highly regarded for their reliability, accuracy, and detailed insights into potential food sensitivities.

These tests are clinically validated and widely used in medical diagnostics due to their ability to deliver precise, science-backed results. By detecting immune responses to specific foods, they help identify possible triggers for symptoms such as bloating, fatigue, and skin issues, making them a valuable tool for anyone looking to understand their body's unique reactions to different foods.

Our test uses advanced microarray technology, where tiny amounts of food extracts are applied to a testing panel alongside calibration standards. Your diluted blood sample is added to the panel, allowing any IgG antibodies in your blood to bind to specific foods if a reaction is present.

The panel is then scanned and analyzed using specialized software, which measures the antibody levels and provides a quantitative, easy-to-understand report showing your potential food sensitivities.

Certain foods can trigger your immune system when your body mistakenly identifies them as harmful substances. This response is often linked to the production of IgG antibodies, which are part of your immune system’s defense mechanism.

Factors like poor gut health, stress, a high-processed diet, overexposure to certain foods, or an imbalanced gut microbiome can contribute to this reaction. Over time, repeated exposure to these trigger foods may lead to symptoms such as bloating, fatigue, headaches, or skin issues—all signs of a possible food sensitivity.

It’s important to note that this is different from a food allergy, which involves IgE antibodies and causes immediate reactions. Food intolerance is usually a delayed immune response and can vary from person to person.

A blood sample test measures your body’s IgG antibody response to specific foods, providing clinically validated, accurate results based on your immune system’s reaction. This method is widely trusted in medical diagnostics for identifying potential food intolerances linked to symptoms like bloating or fatigue.

In comparison, hair sample tests lack scientific backing and do not measure immune responses, making them far less reliable for detecting true food sensitivities.

At TOLEREASE, we use advanced blood testing technology to give you professional, science-backed insights—helping you make informed decisions about your diet and well-being.

Not necessarily. A higher IgG antibody level shows that your immune system has recognized and responded to certain foods, but it doesn’t always mean you’ll experience symptoms. Some people may have elevated IgG levels without any discomfort, while others might react with bloating, fatigue, headaches, or skin issues.

At TOLEREASE, our test is designed to help you identify potential food triggers by providing clear, easy-to-understand results. We always recommend reviewing your results alongside your symptoms and dietary habits. This way, you can make informed, balanced decisions about your diet—avoiding unnecessary restrictions while focusing on what truly benefits your health and well-being.

At TOLEREASE, we recommend our food intolerance test for individuals aged 2 and above. By this age, the immune and digestive systems are more developed, making the results more reliable and easier to interpret. Testing too early may lead to inconsistent results, as younger children’s immune responses are still maturing.

For anyone over 2, our test offers personalized insights into how your body may be reacting to certain foods—helping you better understand potential triggers behind symptoms like bloating, fatigue, or skin issues.

If you’re considering testing for a younger child, we always recommend speaking with a healthcare professional first. Our goal is to ensure every test delivers accurate, meaningful results that truly help guide your diet and well-being.

Yes, certain medications—especially immunosuppressants, steroids, or biologics—may affect your test results by lowering IgG antibody levels. This could reduce reactivity in your results, even if certain foods are triggering symptoms.

We recommend avoiding these types of medications before testing if possible (but always check with your doctor first). Supplements like probiotics or vitamins generally don’t impact results, but it’s still good to inform us or your healthcare provider.

If you’re unsure, feel free to reach out—we’re here to help ensure you get the most accurate and reliable results.

You can upgrade for up to a maximum of 4 weeks from the date that your first sample is received.

Customers should avoid the use of immunosuppressant medication if possible if performing these tests, as they may have an impact upon the results. Please refer to the medication datasheet in the “Support” section for further details.

Our process screens for all IgG subclasses 1-4, with the numbers on the test report representing the total IgG concentration for each food extract in the selected panel.
