Individuals that have a negative result from just one food challenge and open challenge (which confirms the results of the food challenge) are generally able to normally eat those substances to which they test negative. Once a physician has reviewed the test results and determined they are negative, an individual does not need to seek any further treatment for that type of food allergy. If other types of allergens are still suspected, those can be tested by other food challenge tests

A food allergy can result in a deadly reaction if not treated properly. For individuals who positively identify a type of food allergy, avoidance is the key. The only effective type of treatment for people with a food allergy is the complete removal of problem foods from the diet. This is oftentimes a difficult and disruptive practice, but it can completely prevent reactions to a food allergen when diligently observed.

Completely avoiding a certain food type involves education and attentiveness. Food allergic individuals need to learn the different names, forms and extracts of the food they are allergic to. They should conscientiously check the ingredient labels on foods, educate themselves about dangerous cooking techniques and be particularly careful when dining outside the home.
