To facilitate skin prick testing, patients should have discontinued antihistamines (Piriton, hay fever tablets) for at least 3 days prior to the clinic visit. Skin prick test results are available in clinic within 15 min. Most patients will get their skin prick test done during the initial consultation although some may have to get it done in a follow-up visit.
In regards to fruit allergy, we usually request the family to bring the fruits along for modified skin prick testing in clinic. Tests are available for all relevant food and airborne allergens. The 112 allergen test (ISAC) is available on request and a follow-up consultation is done to analyse the results. Tests are also available for lactose and gluten intolerance. The turnaround time for blood test results is between 1-2 weeks.
