The Amsterdam Clinic currently uses two test procedures which have proven to be very reliable. In the cytotoxic test, a drop of the patient's blood is mixed with a drop of pure, liquefied food concentrate. However, in response to lesser degrees of tolerance, these white blood cells swell and possibly granulate. In severe cases the cells will actually blow up and disintegrate. These antibodies are the slowly occurring variety, which do not appear in the blood until 24 to 48 hours after exposure to an offending food or substance.
More moderate reactions allow for rotation of certain food items in the diet.

Concurrently, those complaints relating to food sensitivity also diminish. Using this dietary approach, the reaction to food allergens may decrease in the course of time.
