The best way to diagnose whether a food or drug allergy is truly present or absent is a food/drug challenge. If required, your doctor will arrange a separate appointment for your child to return to our Day therapy centre where he/she will be closely supervised while consuming the suspected food or drug. Only minute amounts of the food will be administered initially while your child is closely observed for any signs of allergy. If he/she tolerates the minute amount without any reaction, the amount will be gradually increased in a series of steps. If your child develops any symptoms of allergy at any point during the challenge, it will be stopped immediately and your child will be treated for the allergic symptoms appropriately.
The total duration of a challenge could last as long as 2-3 hours including the periods required for observation.
