Confirming an allergy often involves a combination of medical history, physical examination, and allergy testing. Your doctor will likely ask about your symptoms, any family history of allergies, and potential triggers.
Here are some common methods used to confirm an allergy:
- Skin prick test (SPT): This is a quick and relatively painless test where a tiny amount of the suspected allergen is applied to your skin. The area is then pricked or scratched, and the doctor observes for any reactions such as redness, swelling, or itching. This test can be used to identify multiple allergens simultaneously.
- Blood test: These tests measure the level of antibodies in your blood that react to specific allergens. They are helpful when skin tests are not possible or reliable.
- Oral food challenge: This is a controlled test where you consume small amounts of the suspected food under medical supervision. The doctor monitors you closely for any allergic reactions.
It's important to remember that no single test can definitively diagnose an allergy. The doctor will use all available information, including your medical history, symptom patterns, and test results, to make a diagnosis.
