Understanding Allergies
An allergy is an abnormal response of the body's immune system to a usually harmless substance, such as pollen, dust, or certain foods. Allergies can cause a variety of symptoms, including sneezing, itching, wheezing, and skin rashes. Although allergies can be uncomfortable and irritating, for some people they can be life-threatening.
Diagnosing an Allergy
If you suspect that you may have an allergy, it is important to see a healthcare provider for a diagnosis. Your healthcare provider can determine the best course of treatment based on your symptoms and history. Diagnosing allergies can be difficult, as there are many possible triggers and the symptoms can vary greatly.
Skin Tests
One of the most common ways to diagnose an allergy is with a skin test. During a skin test, a healthcare provider will apply a small amount of an allergen to the skin, usually on the arm or back. If the skin develops a rash or other allergic reaction, it is a sign that the person may be allergic to the allergen.
Blood Tests
Another way to diagnose an allergy is with a blood test. During a blood test, a small sample of blood is taken and sent to a laboratory for analysis. Blood tests can detect the presence of antibodies, which are proteins produced by the body in response to an allergen.
Elimination Diet
If skin tests and blood tests do not provide a definitive diagnosis, your healthcare provider may recommend an elimination diet. During an elimination diet, common allergens are removed from the diet and then reintroduced one at a time. If a person experiences symptoms after eating a certain food, it may be an indication that they are allergic to that food.
Seek Medical Advice
If you suspect that you may have an allergy, it is important to see a healthcare provider for a diagnosis. Your healthcare provider can help you determine the best course of treatment for your symptoms. If left untreated, allergies can lead to more serious health problems.
