In recent years, awareness of the connection between diet and well-being has increased dramatically. More and more people are reporting persistent digestive problems, skin issues, fatigue, and other symptoms that can be caused by food intolerances. However, without structured guidance and accurate testing, it can be difficult to identify the exact triggers.
YorkTest, a British health and wellness diagnostics company with over 40 years of experience, has established itself as a leading provider of home testing for food intolerances and allergies. The test suite is designed to help individuals make informed dietary changes based on personalized results. But does the scientific evidence support the claims? And—more importantly—are customers actually experiencing benefits?
Founded in 1982, YorkTest Laboratories has grown into one of the most recognized providers of food intolerance testing in Europe. The company operates its own ISO-accredited laboratory and specializes in IgG antibody testing—a method for detecting potential immune reactions to specific foods.
YorkTest’s mission is clear: to provide actionable, science-based insights that enable individuals to optimize their diet, relieve symptoms, and improve their overall quality of life.
The testing procedure is designed for convenience: Blood samples are taken at home from the fingertip, mailed to the laboratory, and analyzed by experienced technicians. The results are accompanied by nutritional counseling to help patients effectively implement their dietary changes.

YorkTest focuses on testing for IgG-mediated food intolerances. IgG antibodies are part of the body’s immune system, and elevated levels can indicate an immune reaction to certain foods. However, the role of IgG in food intolerances remains a subject of ongoing medical debate.
Critics argue that the presence of IgG alone does not always indicate an intolerance, as it can also indicate regular exposure without symptoms. Proponents—and YorkTest itself—claim that avoiding foods with elevated IgG reactivity has helped many people find relief from their symptoms.
YorkTest recognizes this complexity and emphasizes that results should always be interpreted in conjunction with symptoms and professional guidance, not in isolation.
Based on collected online reviews and direct customer feedback, YorkTest has earned a largely positive reputation.

However, a minority of clients reported minimal changes, highlighting that results may vary depending on individual health factors and adherence to dietary recommendations.
YorkTest ships its test kits both within the UK and internationally. Standard delivery within the UK typically takes 1–3 business days, although international delivery times vary by region. Kits are shipped in discreet packaging to protect your privacy.
YorkTest offers a return option for unused and unopened kits within 14 days of purchase for a full refund. Once a kit has been used and the sample submitted, it is non-returnable due to the personalized nature of the testing process.
While no “guarantee” can be given for biological tests in the traditional sense, YorkTest guarantees the accuracy of its laboratory analyses and offers customer support for questions or concerns about the results.
YorkTest offers a structured, user-friendly approach to food intolerance testing, combining laboratory analysis with nutritional counseling. While the IgG test is not without controversy, the many positive customer reviews and long-standing brand credibility indicate that it can be a valuable tool for people with unexplained symptoms.
For those following an elimination diet and working with a qualified nutritionist, the YorkTest can be an important step toward greater wellness. However, as with all diagnostic tools, the results should be viewed in the broader context of medical advice.
If you’re suffering from persistent digestive discomfort, skin irritation, or fatigue and can’t find clear answers, YorkTest offers a reliable, structured way to identify potential dietary triggers. With decades of experience, professional advice, and a focus on empowering the individual, the brand stands out from the crowd of at-home health tests.
