Smartblood Premium Food Intolerance Test
Our Premium Food Intolerance Test provides a comprehensive IgG analysis of 260 individual food and drink reactions, presented in a colour coded format (showing quantities measured in microgrammes per millilitre (ug/ml), with each result additionally colour coded as green amber or red to highlight clinical relevance).
This laboratory test measures food-specific IgG antibodies (subclasses 1–4) in a blood sample. The results provide a snapshot of your IgG antibody levels for the foods tested.
It is important to understand that raised IgG levels do not necessarily indicate a food intolerance. Results should not be used on their own to decide which foods to eliminate from your diet.
Key Features:
• Measurement of IgG antibody responses to 260 foods and drinks.
• Clear, easy-to-follow instructions.
• Free postage and returns.
• Laboratory results sent directly to your email once testing is complete.
• Easy-to-read, colour-coded results report.
• Full refund if no reactions are detected.

Technical Specifications & Methodology
Panel Coverage: The test measures IgG antibody responses to 260 individual foods and drinks.
Sample Collection: A simple at-home fingerprick blood sample collected using the supplied sample card.
Validated Sample Types: The method is fully validated for use with Serum, Whole Blood, and Dried Blood Spot cards (Whatman 903).
Antibody Detection: Measurement of food-specific IgG antibodies (subclasses IgG1, IgG2, IgG3 and IgG4).
Methodology: Quanti-array technology, utilising the standardised ELISA
(Enzyme-Linked Immunosorbent Assay) principle.
Quality Management System (QMS): Laboratory operations are strictly governed by
strict standards including 9 quality check processes throughout the assay process.
Additionally, the test is subject to quarterly external validation in line with the
International Association of Functional Medicine Association standards, involving
benchmark sera. The external quality assurance system (EQAS) ensures clinical and
analytical validity.

Clinical Interpretation Note
IgG and IgE antibodies are different types of antibodies produced by the immune system.
IgE antibodies are associated with allergic reactions to certain foods, which can cause symptoms shortly after exposure.
Food-specific IgG antibodies, however, can be present as part of the body's normal immune response to foods that have been consumed. The presence of these antibodies does not necessarily indicate a food intolerance or sensitivity.
This test measures IgG antibody responses to 260 foods and drinks. It is not designed to diagnose food allergies, food intolerances or anaphylaxis, and the results should not be used alone to determine which foods to eliminate from your diet.
If you experience symptoms that you believe may be related to certain foods, we recommend discussing your results and symptoms with an appropriate healthcare professional.
