My IgE Results

I thought I’d finally have a crack at a blog: I seem to write for hours, switching topic, and never publishing a thing! I’m keeping this one simple by digging out and publishing my old specific immunoglobulin E (IgE) radioallergosorbent test (RAST) results. I say “old” because they date from 2005, when I was 16 years old. The first table details the foodstuff I was tested for, the specific immunoglobulin E concentrations in thousands of units per litre, and a summary of how I handle the foodstuff as far as my exclusion diet goes. The second table classifies specific IgE concentration from negative to strongly positive. Here goes:

Foodstuff Specific IgE (ku/l) Exclusion diet details
Apple 76.10 – Avoid raw apples
– Eat and drink cooked and pasteurised apple in sauces, desserts, juices and cider
Chicken 56.70 Avoid
Egg >100.00 Avoid (including skin contact, which causes swelling)
Milk 2.85 – Avoid raw milk
– Eat and drink pasteurised and sterilised milk, and as cream, yoghurts and cheese
Wheat 12.60 Avoid, except in small quantities such as in gravies
Mixed nuts 79.30 Avoid
Peanuts 90.70 Avoid
Salmon 11.00 Avoid
Sesame 16.00 Avoid
Mixed seafood 18.50 Avoid
Soya 26.20 Avoid, except in small quantities
Turkey 11.70 Avoid
White bean 8.75 Avoid
Specific IgE (ku/l) Result classification
<0.35 Negative
<0.7 Weakly positive
<17.5 Positive
>17.5 Strongly positive

As far as I remember, these are my most recent blood tests. I vaguely recall having a more recent skin prick test but I might have to see if my GP has those results. I know from mishaps that I still react to eggs, wheat, soya and white bean. Of course, the choice of specific foodstuffs in 2005 wasn’t unintentional: at 16 I had a pretty good idea of what was and wasn’t safe! What’s more, the list is far from exhaustive. I avoid all fish and poultry, mushrooms, coconut in large quantities, and pretty much everything in the Fabaceae family (beans and chickpeas) in large quantities. So 13 years on, is it worth a follow-up test? I know for sure I’d like like a breakdown of “mixed nuts”… and I’d be curious to compare all this with my IgE results for my safe foods.
