YorkTest Review Is the At-Home Food Intolerance Test Worth It?

What YorkTest Offers

YorkTest started as a food intolerance testing company and has grown into a broader at-home health testing provider. Its core product is the Premium Food Intolerance Test, which checks IgG antibody reactions to 200 food and drink ingredients from a small finger-prick sample. The Food Allergy Test looks at IgE reactions to 23 foods and 19 environmental allergens like pollen and dust. Bundles combine intolerance and allergy testing, or test two people (the Couples Food Intolerance Bundle), and a Junior test is aimed at children. Beyond food, YorkTest now offers a Gut Microbiome Test, an Annual Health Test, and tests for stress (cortisol), female and male hormones, fertility, menopause, thyroid, liver function, cholesterol, inflammation (CRP), vitamin D and metabolic health.

The Customer Experience

Customers consistently describe an easy process. Order online, receive the kit (free delivery), take a finger-prick sample at home, post it back, and get results online, usually within about a week, according to YorkTest. A 30-minute consultation with a nutritional therapist helps turn results into a plan. Customer testimonials on YorkTest’s site are enthusiastic: “Taking the test was one of my best decisions to date!” and “No headaches, finally leading a normal, much happier life.” Trustpilot reviewers echo that, with one saying “The results came back within 2 weeks and it was amazing.” In YorkTest’s own 2021 survey of 565 customers, 82% reported a positive impact on health and wellbeing.

What the Science Says

This is the most important part of any YorkTest review. Its food intolerance tests measure IgG antibodies. IgG reactions often reflect foods you eat regularly, and many allergy and immunology organizations say IgG testing isn’t a validated way to diagnose food intolerance. YorkTest is upfront about this: its site states that food-specific IgG results “cannot be used to diagnose, treat or medically cure any specific food intolerances,” and are “for informational purposes only.” Many customers still find the results useful as a starting point for a structured elimination diet, especially with the nutritionist consultation. Some customers dispute their results, though. One wrote “They told me I had no reaction to eggs. How wrong!” Anyone with suspected true allergies, especially severe reactions, should see a doctor.

Sampling, Accreditation and Value

YorkTest’s laboratory is ISO 13485 certified and holds IBMS pre-registration approval, which gives confidence in sample handling and processing. The finger-prick sample is the step most likely to go wrong. One customer said “the absorber wand didn’t fill up with blood no matter how hard I tried.” Warm your hands, drink water beforehand, and follow the instructions closely. At £139 for the Premium Food Intolerance Test (currently discounted from £199) and £230 for bundles, it’s a meaningful spend. It makes most sense for people who’ll use the results with the nutritionist consultation as part of a guided plan, rather than cutting out foods on their own.
