“My life was changed for the better and I’m really grateful to YorkTest for helping identify my problems”


72-year-old retired analyst Susan McAdam had been suffering with Irritable Bowel Syndrome (IBS) for a number of years, with the condition getting progressively worse.

She explained how these symptoms had affected her during this time, “I was struggling with constant pain, bad skin issues and lactose intolerance. Virtually every day I had to take some sort of pain medication. ”

Susan learned about YorkTest after seeing a Youtube video on IBS, “I was so impressed that I ordered a test.”

After taking a Premium Food Intolerance Test, Susan found she had IgG reactivity to egg yolk, garlic, dairy and gluten among other ingredients . After eliminating her trigger ingredients, her symptoms began to take a turn for the better.  “It was about two weeks before I really noticed the overall inflammation was going away and I ended up losing about 10 or so pounds. Yay!”

Talking about her experience with trying to eliminate multiple foods from her diet, Susan said, “I’ve had to establish different eating habits, but it’s a work in progress and so far I am happy with it.”

Susan added, “When you are eliminating pain, it’s surprising how easy it is to avoid a food. Yes, I still miss pizza, cheese, real bread, dairy etc., but I don’t miss that constant nagging pain. Without eating the trigger foods, I usually feel pretty decent.”

YorkTest analyses your IgG reactions to 200 food and drinks – from common ingredients like Cow’s MilkGluten and Egg, to health superfoods like kale and quinoa.

The process, which involves sending a finger-prick blood sample to the company’s laboratories revealed Susan’s intolerances. Following on from the test, we asked Susan how she found the customer service experience to which she replied: “Amazing. Very nice people.”

When asked to sum up her whole experience with YorkTest, Susan concluded: “My life was changed for the better and I’m really grateful to YorkTest for helping identify my problems.”
