Junior food intolerance test - York test

[mamadoesntknowbest]

In a moment of madness I bought a York test junior food intolerance test for my son (just 2) as he’s been having a lot of very unexplained loose nappies first thing in the morning. No weight loss, generally good mood (apart from the tantrums) and eating fine apart from a bit of fussiness. Lots of farting!
Did the test (small blood test) and it’s showing his iGc reaction level is 87 out of 100 for cows milk so highly intolerant! 68 out of 100 for wheat. I don’t know how much to trust these sorts of tests but I bought one as thought it would be quicker than getting anything on NHS.
I wonder if he’s that intolerant given he’s generally happy?
Anyone else used them and what was your take on them?

These tests are an absolute scam, ignore the numbers.

"toddler diarrhoea" is really common in this age group and may respond to simple dietary changes. Some children also get loose stools if they are big fruit-eaters as many are.

Unfortunately these tests are not reliable.
My daughter has delayed food allergies sometimes referred to as intolerance depending on the professional. We had to carefully remove each food and then retry them to see if symptoms return
She also had toddler diarrhoea and having loose poos first thing in the day/early morning and having undigested food in them were two of the signs that her drs put it down to toddler diarrhoea rather than further food reactions. High fat, low fibre and avoiding grapes and dried fruits are meant to help. A few of her friends in the NCT group had loose stools around the same time and they found that increase fat in their diets made a difference

These commercial tests are snake oil I'm afraid. If it was so easy to diagnose allergies and intolerances I am pretty sure the NHS would be using them rather than employing immunologists and gastroenterologists!
The only reliable tests for allergies are skin prick testing and specific IgE blood tests (previously called RAST testing) which can only identify IgE mediated allergies that give the classic allergic response of things like hives, swelling, wheezing and so on. And even they need to be interpreted by someone who knows what they are doing, alongside a full history. There are no tests for non IgE mediated allergies other than exclusion/reintroduction. Some other food intolerances like lactose intolerance which is due to shortage of a digestive enzyme do have specific tests but you need to see a doctor for those too.
If you are concerned OP you need to see your GP and ask for a referral. It would be unwise to exclude major food groups from a growing child's diet without professional advice, especially when they may not be intolerant of those foods at all.
