Identifying the source of persistent symptoms, such as sneezing, rashes, or breathing difficulties, is the first step toward lasting relief. An allergist uses specialized testing to pinpoint specific triggers, whether they’re environmental, food-related, or otherwise. Here’s what to expect during allergy testing with an allergist:
Initial Consultation
Your first visit begins with a detailed discussion about your symptoms and medical history. The allergist will ask about when your symptoms occur, what triggers them, and how severe they are. This conversation helps determine which allergens to test for and which testing methods will be most effective.
The allergy specialist will also review your family history of allergies. They may ask about medications you take, since some can affect test results. You may need to stop taking certain allergy medications before your appointment. During this consultation, your allergist explains the testing process. They will discuss what to expect and answer any questions you have about the procedures.
Types of Allergy Tests
Healthcare providers use three main types of allergy tests to identify triggers. Each test checks for different allergens and provides specific information about your reactions. They are:
- Skin prick tests: Your allergist places small amounts of potential allergens on your skin, usually on your forearm or back. They then make tiny scratches or pricks through each drop to let the allergen enter your skin.
- Skin injection tests: This involves injecting small amounts of allergens just under the skin using very fine needles. This method is helpful when skin prick tests don’t provide clear results or when testing for specific allergens, such as insect venom.
- Blood tests: This requires a sample of blood, which is analyzed in a laboratory to identify triggers like pollen, pet dander, or food allergens. Although the results may take longer compared to skin tests, blood tests offer a valuable alternative for identifying allergic sensitivities.
Both skin and blood tests provide key insights into allergen sensitivities, enabling allergists to develop tailored management and treatment plans for individuals.

What Happens During the Testing Process
Before testing begins, your allergist cleans the test area on your skin. For skin prick tests, they mark small sections where each allergen will be placed. You may feel a light scratch or prick, but the discomfort is minimal.
After applying the allergens, you wait about 15 minutes while your skin reacts. During this time, you should avoid scratching or rubbing the test areas. The allergist monitors you for any signs of severe reactions, though these are rare.
Your skin develops small, raised bumps called hives if you’re allergic to a specific substance. These bumps appear red and may feel itchy. The size of each hive helps determine how allergic you are to each of the tested substances.
Results and Next Steps
Your allergist examines your skin reactions and measures any hives that develop. Larger hives typically indicate stronger allergic reactions to those specific allergens. They record these measurements to create a complete picture of your allergies.
Test results are available immediately after the conclusion of the observation period. Your allergy care provider explains what each reaction means and how it relates to your symptoms. They discuss which allergens to avoid and what treatments can help manage your reactions. Based on your results, your allergist develops a personalized treatment plan. This may include medications, lifestyle changes, or allergy shots to help reduce your sensitivity over time.
