Hi. Me again! Wearing this forum out I think....
Food allergy testing. I am going for some blood tests for food allergy testing. In other posts I've mentioned I'm having coeliac reaction to a whole new range of non-gluten foods, and it's all a bit confusing.
Can anyone tell me if the igE blood test for allergies is the same as coeliac, i.e. you need to have the food in your diet to register any allergy reaction?
I asked this of the GP and they stated a small level of igE should register even if food not in diet for a while. I'm not convinced by that, and do not think it will be a valid allergy test in the absence of the food items being tested for.
Anyone had similar, or have any thoughts on this?
So, basically will a blood test accurately measure if you do/do not have an allergic response to a food it that food has not been in your diet for years.
Think I'm entirely sceptical when it comes to GPs and diet issues at this point.
