For years, I struggled with recurring digestive problems, unpredictable bloating, and sudden bouts of fatigue. I tried the usual remedies—keeping a food diary, avoiding dairy and gluten—but nothing really helped. After another frustrating cycle, I decided to try YorkTest, a British provider of at-home food intolerance testing.
Given the high price, I wanted to know if this test would truly help me identify my problem foods—or if it would just be another expensive experiment. Here’s my detailed, experience-based review.
YorkTest Laboratories has been in business for over 40 years and specializes in food intolerance testing using IgG antibodies. The company operates its own ISO-accredited laboratory and focuses on personalized at-home testing to uncover potential food triggers.
What sets them apart from some cheaper alternatives is their all-round service—you not only get a list of foods to avoid, but also nutritional advice to help you create a sustainable elimination plan.
The ordering process was straightforward. Within two days, I received a discreetly packaged kit. The kit contained everything I needed: a lancet, a collection card, alcohol swabs, plasters, and step-by-step instructions.
The finger prick was quick and only slightly uncomfortable. I filled the blood collection card with a few drops, put it in the prepaid envelope, and mailed it back.
It took seven business days for me to receive my results via email. The report was clear, color-coded, and categorized foods into high reactivity, moderate reactivity, and low/no reactivity.
I had a 30-minute phone call with a nutritional therapist. She explained how my IgG reactivity levels might be related to my symptoms and helped me develop a gradual elimination diet, starting with the most reactive foods.
I was surprised that eggs, almonds, and cow’s milk were at the top of my reactivity list—especially since I consumed these foods almost daily. Gluten showed only a slight reactivity, while most fruits and vegetables were within the safe range.
The nutritionist recommended removing the most common triggers for at least 8 weeks and monitoring symptoms. Then, gradually reintroducing them to assess tolerance.
Within three weeks, I noticed noticeable changes:
Not all symptoms disappeared completely, but the improvement was enough to convince me that it was worth acting on the results.
YorkTest offers free standard shipping within the UK. Most kits arrive within 1–3 business days. International shipping is available for an additional charge.
Unused, unopened kits can be returned within 14 days for a refund. Once a sample has been sent to the laboratory, no refunds are possible.
While there is no traditional guarantee for biological results, YorkTest guarantees accuracy and will retest free of charge in the event of a laboratory error.
In my case, yes. The test not only provided me with data, but also a clear, actionable plan that actually alleviated my symptoms. Consulting a nutritionist made a huge difference, transforming the lab results into practical lifestyle changes.
It’s not a miracle cure and requires commitment, but for anyone struggling with unexplained digestive problems, skin issues, or fatigue, YorkTest can provide valuable insights that justify the cost.
YorkTest is a high-quality, professional food intolerance testing service ideal for people who want to adjust their diet based on the results. While the price is rather high, the combination of laboratory accuracy, detailed reports, and personalized nutritional advice makes the test a worthwhile investment for many.
