This test exposes your child to their possible trigger, usually a food or drug. The aim is to set off their allergy, if it exists, under medical supervision. Your healthcare provider monitors your child for any reaction. Your child will need to stop taking antihistamine before the challenge as it can mask symptoms. Of course, always follow your healthcare provider's instructions.
Oral food challenge (OFC): May be the next step when other tests are inconclusive or to see if a child has outgrown a food allergy. The food challenge starts with a tiny amount of the potential trigger and increases gradually. If your child reacts, you know they must avoid certain foods.
The clinic may ask you to bring food with you for the test, particularly for little kids and fussy eaters. It can be calming to have a favorite plate and utensils. And toys as you’ll have to wait for a few hours after testing in case of a delayed reaction.
