Please note that this test works by measuring how you respond to foods that you have eaten. Therefore, it is important to follow your normal diet before taking the test so that the test results will reflect what you usually eat.
Do not eat any food which has already caused a severe reaction without first getting a medical opinion.
Reintroducing a food for the purpose of doing this test
The ideal is eating your normal diet leading up to the test. Get your doctor’s advice on any food you’ve excluded but want to re-introduce for the purpose of doing this test. If approved by your doctor, include one portion per day for 5-7 days before collecting the blood sample.
- Cow’s milk (dairy products) can be problematic for some people and goat’s products (cheese, yoghurt) is for many people a good alternative. Soya products and especially organic soya is another good alternative.
- Potato intolerance is common and sweet potato is a possible alternative. Spelt bread makes for a good alternative for wheat sensitive people.
However, to confirm if these are good alternatives for you it is important that you include them in your diet for five to seven days before doing the test.
The IgG antibodies remain in your bloodstream for approximately two to three month’s so your test will be assessing your reaction to foods you have eaten over that period.
Please refer to the website for a list of foods that will be checked on your chosen test.
