What is allergy testing?

Allergy testing encompasses several methods used by allergists to determine what substances you may be allergic to. When you have an allergy, your immune system mistakenly reacts to a substance as if it is harmful or dangerous. The substances that trigger allergic reactions are called allergens.  

What substances can trigger allergic reactions?

Some of the most common allergens are:

• Foods (most common are milk, egg, peanut, tree nuts, soy, wheat, sesame, fish, and shellfish)
• Pollen (from trees, grasses, and weeds)
• Fungus (molds and mildews)
• Animal dander (e.g., dogs, cats)
• Insects (e.g., bees, wasps, fire ants, cockroaches)
• Dust mites (microscopic arachnids that live in the dust)
• Medications and supplements
• Various chemicals, fragrances, and cosmetic products
• Latex

What symptoms are caused by allergic reactions?

When you have an allergy, your immune system mistakes certain proteins for pathogens and releases chemicals called histamines to fight them off. This reaction causes uncomfortable symptoms, such as:

• Sneezing
• Itching
• Red, watery eyes
• Skin rash
• Hives
• Wheezing
• Swelling
• Chest tightness

Allergies can also cause a severe response called anaphylaxis, which may lead to breathing difficulties, rapid heartbeat, and low blood pressure.

Allergy and Asthma of Prosper and Celina offers multiple types of allergy testing, including:

• Skin prick testing
