No, this is not normally necessary. Even if a new test does not detect particular antibodies, this does not mean that you can recommence eating all the foods and additives to which an intolerance was detected. The immune system has a memory and reactivates the production of antibodies when it comes in contact with a food or additive which it has previously had a reaction to. However the production of antibodies is generally reduced through implementing the necessary diet changes as the antibodies are no longer created by the immune system when the diet is changed. The resumption of the natural function of the intestine is an indicator that the production of antibodies has been reduced. The test would only need to be repeated if the symptoms were to reoccur, though this would be unlikely if you are keeping to your diet and rotation plan instructions. If the test is to be repeated it is recommended that two years elapse between tests.
