Why this test
Broader panel
286 antigens across 13 food groups, more than most UK competitors.
Full IgG range
Subclasses 1, 2, 3 and 4 analysed, not just one.
Regulated lab
Processed in our own CQC-regulated UK lab, not outsourced abroad.
Faster results
3–7 days, quicker than the 7-day standard elsewhere.
Clear, colour-coded results
Your results are grouped by food group, with each item shown on an easy-to-read scale from negative to highly elevated IgG reactivity, no clinical jargon required.
Illustrative sample only, showing how your own results will be presented across all 13 food groups.
The technology behind your results
Nano-bead multiplex testing
Your sample runs through the FOX platform's multiplex assay, which screens for reactivity across all 286 food antigens in a single pass, rather than testing one food at a time. Each result is calibrated and quality-checked before it reaches your report.
Could this test help you?
Some people explore food-specific IgG testing when they experience ongoing bloating, fatigue, digestive discomfort, or skin issues that may be linked to certain foods in their diet. This test gives insight into your IgG reactivity to common food antigens, which some people use to inform dietary changes alongside advice from a GP, dietitian, or nutritionist.
Frequently asked questions
What does the Food Intolerance Test measure?
The test measures IgG antibody reactivity to 286 food antigens across 13 food groups, covering IgG subclasses 1 to 4. It is a dietary insight tool, not a diagnostic test for allergy or disease.
How is the sample collected?
You collect a small finger-prick blood sample at home using the kit provided, then post it to our CQC-regulated laboratory using the prepaid return envelope.
How long does it take to get results?
Results are typically available within 3 to 7 days of your sample being received at the laboratory.
Is a food intolerance test the same as a food allergy test?
No. This test measures IgG antibody reactivity, which relates to food intolerance, not IgE-mediated allergy. If you suspect a food allergy, seek advice from your GP or an allergy specialist.
Is this test regulated?
Yes. Your sample is processed at London Health Company, a CQC-regulated laboratory, using the FOX platform's nano-bead multiplex technology.
