YorkTest gets 4.8 / 5 on Trustpilot for an easy finger-prick kit, results in about a week and helpful nutritionist support. But the British Dietetic Association and the American Academy of Allergy, Asthma & Immunology say IgG food testing isn't scientifically validated for diagnosing food intolerance.

01 Why We Reviewed YorkTest
YorkTest is a UK-based at-home testing company best known for its Premium Food Sensitivity Test (£199 / $199). It claims to measure food-specific IgG antibodies (four subtypes) to 200 foods and drinks. The process is simple: you prick your finger, fill a small absorbent wand with blood, post it back in a prepaid envelope, and get results online within about a week. The kit includes lancets, the collection wand, protective packaging, a plaster and a cleansing wipe. Trustpilot reviewers frequently mention follow-up calls from nutritionists and helpful customer service. A Junior version is offered for under-18s.
The honest caveat is the science. The British Dietetic Association states "no convincing evidence supports this test" and doesn't recommend it for diagnosis. The American Academy of Allergy, Asthma & Immunology says IgG to foods is likely a normal immune response, not a marker of intolerance. A dietitian review warns that restricting foods based on results can risk nutritional deficiencies and may contribute to disordered eating, and notes that symptom improvement after testing may partly reflect reduced anxiety. The recommended approach is a supervised elimination and reintroduction diet, after a doctor has ruled out other conditions.

04 How to Use YorkTest Responsibly
Based on expert guidance, here's how to approach it.
See a GP or Doctor First
Most Important Step
Rule out coeliac disease, IBS, allergies and other conditions before testing. Food sensitivity tests aren't allergy tests.
Use Results as a Starting Point Only
Best Approach
If you do test, treat results as ideas for a short, supervised elimination and reintroduction plan, not as a list of foods to avoid permanently.
Work With a Registered Dietitian
Recommended
A dietitian can make sure any temporary restriction stays nutritionally balanced and that foods are reintroduced.
Cutting Many Foods at Once
Approach With Caution
Removing large numbers of foods based on IgG results risks deficiencies and an unhealthy relationship with food.
05 What Buyers Are Actually Saying
A customer on ease of use:
Very easy test to complete at home and fast response time after completion.
Another on service:
Spoke to customer service rep Daniel who was lovely and very helpful.
On the concerns side, a customer on collection:
The absorber wand didn't fill up with blood no matter how hard I tried.
And one on accuracy:
I don't trust Yorktest.
The pattern: customers love the process and support, while doubts focus on whether the results are accurate or meaningful.

See a GP and Registered Dietitian First — then consider YorkTest only as a guide
If you buy the YorkTest Premium Food Sensitivity Test, follow the collection instructions carefully (warm hands help blood flow), and treat any results as a short-term, supervised experiment with reintroduction, never as a reason to permanently restrict foods.
