Food Allergy/Intolerance Testing
Food Intolerance is similar to an allergy, the reactions are the same but the timeframe is different.
If you have an allergy it is the IgE part of the immune system reacting and is an IMMEDIATE reaction, ie - you eat a strawberry and your lips swell up or you start sneezing etc.
An intolerance is the IgG part of the immune system and is a DELAYED reaction. You may eat a food and not react for 2-3 days. It is further complicated by the fact that it is also CUMULATIVE, meaning that you may eat the food several times and be ok and then one more time and you react, OR several foods may be involved eg - cheese one day, egg the next, then a banana and a reaction.
For these reasons, intolerances are difficult to identify with food eliminations.
The intolerance test is a simple finger prick blood sample taken in the clinic. We then send this to a lab in the US where it is tested for delayed hypersensitivity reactions to 96 foods commonly consumed in the Western diet (vegetarian and Asian panels also available).
We use the lab in the US as they have the best record for precision and reproducability of results.
The other thing I love about this test is you get a degree of reactivity, not just a yes or no answer. So you can see which foods must be avoided altogether and which you react to but can consume once or twice a week.

Cheddar Cheese Apricot
