Allergy Testing

Allergy testing is a crucial diagnostic tool used to identify the specific substances causing allergic reactions. These tests are essential for managing allergies effectively, as they help pinpoint the allergens responsible for symptoms such as skin rashes, breathing difficulties, or digestive issues.

What does the test look for?

Allergy tests typically look for the presence of specific antibodies, known as Immunoglobulin E (IgE), in response to potential allergens. These allergens can range from common food items like peanuts and shellfish to environmental factors like pollen or dust mites. However, the exact set of allergens tested can vary depending on the provider.

How can this test help you?

Understanding the specific allergens that trigger your symptoms can guide effective treatment and management strategies. This knowledge can help you avoid allergenic substances, adjust your diet or environment, and choose the right medication or therapy.

Help Choosing

When exploring options for allergy testing understanding the differences between Skin Prick Testing, Blood Allergy Testing (Specific IgE RAST), and Patch Allergy Testing is crucial to choose the most suitable method based on individual needs and the type of allergies suspected:

Skin Prick Allergy Testing: A quick and common method for diagnosing airborne, food, and some drug allergies. Small amounts of potential allergens are pricked into the skin's surface, usually on the forearm or back. If you're allergic, a small raised bump appears at the test site. It's fast, with results typically available within 20 minutes, making it a preferred choice for immediate hypersensitivity reactions. However, it might not be suitable for those with severe skin conditions, certain medication use, or extreme allergic reactions.
Blood Allergy Testing (Specific IgE RAST): This test measures the amount of allergy-causing antibodies in your blood, known as IgE antibodies. It's useful for individuals who can't undergo skin testing due to skin conditions, medication interference, or a history of severe allergic reactions. It's less sensitive than skin prick tests and more expensive, but it's safer for those with a risk of severe reactions and can be used to confirm skin test results or when skin testing isn't possible.
Patch Allergy Testing (Skin Patch Testing): This test is used primarily to diagnose contact allergies, such as to latex, fragrances, preservatives, or metals. Allergens are applied on patches, which are then placed on your skin, typically on the back, for 48 hours. It's useful for identifying delayed allergic reactions, which can take several days to develop. This test is not suitable for food or airborne allergens and is less commonly used than skin prick or blood tests.

In choosing the right allergy test, consider the types of allergies you suspect (immediate vs. delayed), your medical history, current medications, and any previous allergic reactions. Each test has its strengths and limitations, and in some cases, a combination of tests may be recommended.
Consider consulting with a GP or with an allergist or immunologist who can provide tailored advice and help you select the most appropriate testing method for your specific situation.
