Reasons to consider performing an OFCT:
(1) initial identification of foods causing an allergic response
(2) monitoring resolution of a food allergy
(3) determining if a food associated with a chronic allergic condition like atopy is able to cause an immediate reaction
(4) expanding the diet of a patient with multiple dietary restrictions
(5) determining the tolerance of cross-reacting foods
(6) determining if cooking or other food processing can make a food tolerable to the patient
Reasons to defer performance of an OFCT:
(1) high probability of having a serious reaction to the food
(2) history of anaphylaxis or unstable asthma following exposure to the food
(3) presence of a medication or condition that may interfere with the interpretation of the results
(4) presence of a medication or condition that may make an allergic reaction or its treatment hazardous to the patient
