Allergy testing helps identify substances that may trigger an allergic reaction. These tests work by exposing you to suspected allergens, and then your body’s response is observed. Understanding what the results mean is a key part of managing your health, because this information helps you make sense of the report your provider gives you. Here is more information about allergy testing results:
Skin-based Tests
A standard method for allergy detection is the skin test. During this procedure, a small amount of an allergen is applied to your skin, which is then scratched. This introduces the substance into your system, and the test is performed in a controlled medical setting.
The test administrator looks for a specific reaction. If you are allergic, a reaction typically develops quickly. These tests provide quick answers, and they do require you to avoid certain medications beforehand. The results are measured and recorded for later comparison.
Raised Bumps
A positive skin test result appears as a raised, red bump. The size of this bump is measured to gauge the level of your sensitivity. A larger bump generally suggests a stronger allergic response. Your healthcare provider documents the measurements for each allergen tested.
Bumps indicate the presence of specific antibodies in your skin. When they encounter an allergen, these antibodies release chemicals that cause localized swelling and redness. It is the size of the bump, not just its presence, that provides detailed information.
The area around the bump may also become red, which is called a flare. The flare is also measured, and its dimensions are recorded. Both the bump and the flare contribute to the overall interpretation of your test results. Your provider will explain what each specific reaction signifies for you.
Elevated Antibodies
Blood tests offer a way to confirm allergies. These tests measure the amount of antibodies in your blood. When your body encounters an allergen, it produces specific antibodies to fight it. The lab will check for elevated levels of these antibodies.
This method is useful for people who cannot undergo skin allergy testing. A blood test is a single lab draw, so it does not require multiple skin pricks. Conditions that might prevent skin testing include:
- Severe skin conditions
- Severe allergic reactions
- Various medications that interfere
High levels of antibodies to a certain substance suggest a possible allergy. A report details the specific antibody levels for each allergen tested. This gives your provider another piece of information to work with.
Compared Results
Your provider will interpret your test results in the context of your medical history. A positive test result does not automatically mean you will react every time. A test may show a sensitivity, but you may not experience symptoms in your daily life. Your reported symptoms are a large part of the diagnostic process, and your provider compares the skin or blood test results with your personal health records.
