Allergy testing is the best way to determine the cause of an allergic reaction. From a wide range of foods to dust or mold, it is possible to be allergic to almost any substance. However, diagnosing the allergens responsible for allergic reactions is not always straightforward. Working with your Atlanta allergist, it is possible to get a precise diagnosis using allergy skin testing.
Skin Testing For Allergies
Skin testing is the fastest way to diagnose an allergy, with results delivered in as little as 15 minutes. The different types of skin testing for allergies can be conducted at your allergy doctor’s office under close supervision. The results can then be used to develop a treatment plan that reduces the risk of an allergic reaction. The main types of allergy skin testing are skin prick tests and skin patch tests.
What Is a Skin Prick Test?
A skin prick test detects allergic reactions to substances like food, pollen, mold and pet dander. The test aims to measure the concentration of immunoglobulin E (IgE) antibodies by monitoring reactions on the skin. Substances suspected of causing allergic reactions – potentially up to 50 allergens – are placed on the forearm or back and a needle punctures the skin beneath.
Shortly after the introduction of the substance, a red and itchy hive may appear on the skin. This reaction is confirmation that you are allergic to the substance.
What Is a Skin Patch Test?
The skin patch test differs from a skin prick test in that it focuses on contact skin allergies as opposed to reactions from food consumption or airborne allergens. Skin prick test results are delivered within an hour, but skin patch results take about 48-96 hours.
With a skin patch test the process involves placing patches containing various allergens onto the back. Patches are worn for approximately 48 hours and the subsequent presence of a rash confirms an allergy.
If you suffer from contact dermatitis or hypersensitivity to chemicals, rubber, metals, cosmetic ingredients and foods more often than not, your allergist will recommend a skin patch test.

Professional Allergist Testing vs. Home Testing Kits
Because a skin allergy test is the quickest way to detect an allergy, the process has made its way into home test kits. With the prevalence of home skin testing and products that allege to detect allergen sensitivity, many people believe they can get accurate test results in the comfort of their own homes.
However, the reality is that most home testing is inaccurate, increasing the importance of visiting an allergy clinic. A visit to a professional allergist takes less time than many people assume, and your allergist will assess your symptoms, review the relevant medical history – and use professional-grade skin testing for accurate results.
What Treatments Are Available After Allergy Testing?
If testing confirms you have an allergy, your allergist will advise on the best treatment option. While avoidance of an allergen can minimize risks, long-term results can be achieved with immunotherapy. Immunotherapy treatment desensitizes the body to allergens through gradual exposure over many months.
