Types of Allergy Tests:

Skin Prick Test (SPT): This is the most common allergy test performed by healthcare professionals. During an SPT, a small amount of allergen extract is pricked onto the skin's surface, usually on the forearm or back. If you're allergic to the substance, you'll develop a localized reaction, such as redness, swelling, or itching, within 15-20 minutes.

Blood Test (Specific IgE Test): Also known as a radioallergosorbent test (RAST) or allergen-specific immunoglobulin E (IgE) test, this method involves drawing blood and testing it for the presence of specific antibodies (IgE) produced in response to allergens. Blood tests are useful for individuals who cannot undergo skin prick tests due to certain medical conditions or medications.

Patch Test: Patch tests are used to diagnose contact dermatitis, a type of allergy that occurs when the skin comes into contact with certain substances. During a patch test, small patches containing various allergens are applied to the skin, typically on the back. The patches are left in place for 48 hours before being removed and examined for any allergic reactions.

What to Expect During the Test:

Before undergoing an allergy test procedure, experts of Advanced Allergy and Asthma Care, PLLC will review your medical history and discuss your symptoms in detail. They may also conduct a physical examination to assess any visible signs of allergic reactions. Once the appropriate test is determined, the procedure typically follows these steps:

  • Preparation: Depending on the type of test, you may be instructed to stop taking certain medications that could interfere with the results.

  • Skin Prick Test: The skin is cleaned with alcohol, and a grid is drawn on the testing area to label different allergens. A drop of allergen extract is then placed on each marked spot, and a small lancet is used to prick the skin through the droplet.

  • Blood Test: A healthcare professional will draw a small sample of blood from a vein in your arm using a needle and syringe. Then the blood is sent to a laboratory for examination.

  • Patch Test: Adhesive patches containing allergens are applied to the skin and secured with hypoallergenic tape. You'll be instructed to keep the patches dry and avoid excessive sweating or activities that could loosen the patches.

By understanding the allergy test procedure, you can take proactive steps towards identifying and addressing your allergic triggers. So, if you are looking for an ‘allergy doctor near me’, you can contact Advanced Allergy and Asthma Care, PLLC right away.
