    How do I find out if I have an allergy?

    If you believe you or a family member may be suffering from an allergy or have been experiencing symptoms which have no traceable cause, allergy testing is available from IGP.

    The main difficulty with testing is narrowing the possible triggers or causes. The main causes of allergic reactions tend to be in most food products, clothing or even in the natural environment.

    Before starting allergy testing, it is advised to keep a diary of when any reactions occur and what you were doing/eating just prior to the reaction. That way you can narrow down your possible triggers to the smallest amount. There are allergy profile tests, which test for the most common causes of allergies as a group.

    One advantage of testing, even if you are unable to identify which substance is causing the reaction, is that even with a negative result you can rule it out as a trigger and therefore no longer have to avoid that substance.
