Allergy testing is a process that subjects you to many different types of potential allergens to determine which ones you’re allergic to. If you often have allergic reactions and want to put a stop to them or at least learn to manage them, then you need to identify exactly which one is likely causing such allergic reactions.
In Southeast Asia, allergy testing can be done in three ways. The first is called the skin pricking or skin-scratching test. It involves the health care provider pricking or scratching the skin, usually on the forearm, upper arm or back with the allergen and then waiting for 15 to 20 minutes to check for a reaction. If there’s a positive reaction, the skin most commonly shows “wheals.” This is the fastest way of allergy testing as it checks against several allergens at a given time.
The second allergy test is also done through the skin but involves an intradermal needle. Instead of just pricking or scratching, the allergens are injected into the skin of the arm or forearm. This option is used when the skin prick test yielded negative results but the health care provider still wants further confirmation.
The third type is called patch skin test and involves applying a patch with allergens on it to the skin for 48 hours. The results will be observed after 72 to 96 hours. If you have limited time to spend in the region and require immediate result, getting the first allergy test is highly recommended.
Allergy testing is only the first step in managing your allergic reactions. The good thing about it is that you can combine your allergy testing when you go for a holiday in Southeast Asia. Doctors and health professionals are highly qualified to administer the tests and their professional fee is just a fraction of what you’ll pay in western countries.
