Allergy Testing
What is Allergy Testing?
Healthcare providers use allergy testing to identify the substances (allergens) that are causing your symptoms. During this test, your healthcare provider evaluates your body’s response to chemicals that are not present in a controlled environment. Caused by natural factors such as mold, jealousy, and instability. Some people get sick from bee stings, bees, or other foods such as peanuts, milk, or soybeans. Your physical exam will help you determine what is causing your symptoms, and your doctor can develop a treatment plan to address your problem. This test is safe and reliable for identifying allergies.
What are the types of allergy tests?
- Skin Prick (scratch) test
- Intradermal skin test
- Patch test
- Blood (IgE) test
- Oral challenge test
Skin Prick(scratch) Test: A skin prick test uses a small needle or scratch to expose your skin to allergens and checks for redness or bumps within 15 minutes, helping detect common allergies like food, pollen, or penicillin.
Intradermal Skin test: If the skin prick test doesn’t give clear results, an intradermal test involves injecting small amounts of allergens into your skin to check for reactions to air irritants, medications, or insect stings.
Patch test: This test checks for skin rashes by placing an allergen on your skin with a bandage, which you wear for 48 to 96 hours before your doctor checks for reactions.
Blood igE test: A blood test checks for allergies by measuring IgE antibodies to see your overall allergy levels or reaction to specific allergens.
Oral Challenge test: A blood test checks for allergies by measuring IgE antibodies to see your overall allergy levels or reaction to specific allergens.
Why do healthcare providers perform allergy tests?
Your doctor might recommend an allergy test if you have bothersome allergy symptoms or if you have asthma. Allergy tests can help find triggers that may make asthma worse, known as allergic asthma. If you’ve ever had a severe allergic reaction called anaphylaxis, testing can help identify the cause. Anaphylaxis is a serious condition that can cause symptoms like swelling, hives, trouble breathing, or a dangerous drop in blood pressure. Based on your health history and test results, your doctor can determine what caused the reaction.
