Important Considerations Before Testing
-
If a client has been avoiding certain foods for more than six weeks, their IgG levels for those items may not register in the results.
-
If they are avoiding foods due to known reactions, we do not recommend reintroducing them solely for testing purposes.
-
However, if they would like those foods to be included in the test, they would need to consume them 2–3 times per week for six weeks prior to testing.

We also offer food allergies IgE and environmental tests: £129 (RRP £199). Tests for 23 foods & 19 environmental allergens.

Food Intolerance test kit
Can be ordered, as the results come with an easy to understand report, so you don't require a full consultation. In this example only, I will look over the results and request a review if necessary. However, a consultation is recommended to ensure this is the right test for you.
