How Allergy Tests Are Done: Dr. Charlot Explains!

Allergy testing is a simple and informative process that helps identify specific allergens triggering your allergy symptoms. The most common types of tests are skin prick tests and blood tests. During a skin prick test, a healthcare professional applies tiny amounts of common allergens to your skin, usually on your forearm or back, using a small, sterile tool. If you’re allergic to a substance, a small, itchy bump (similar to a mosquito bite) will appear within 15–20 minutes. This test is quick, minimally invasive, and provides immediate results, making it a popular choice for diagnosing allergies.

Blood tests, on the other hand, are used to measure the presence of allergen-specific antibodies in your bloodstream. These tests are particularly useful for people who cannot undergo skin testing, such as those with severe skin conditions or those taking medications that could interfere with results. A simple blood draw is sent to a lab where it’s analyzed for various allergens, and results are usually available within a few days. Both methods are safe and effective, providing vital insights to guide treatment plans tailored to your specific needs.
