Allergens are substances that cause an allergic reaction. There are three main types of allergens:- Respiratory allergens that cause sensitivity when they enter the lungs, nasal passages and throat... Pollen is one of the most common respiratory allergens.
- Food allergens that exist in some foods such as peanuts, soybeans and seafood and lead to food allergies.
- Contact with allergens that usually cause a reaction on contact with your skin... An example of this reaction can be redness and itching after contact with poison ivy...
During allergy testing, they expose you to a small amount of the allergen and record your body's reaction.

Elimination regimen
An elimination diet can help your doctor determine the allergenic foods that cause allergic reactions in the patient's body. This diet removes certain foods from your diet and then adds them back to your diet. Your reaction helps identify the allergenic food.
Dangers of allergy testing
Allergy testing can cause mild itching, redness, and swelling of the skin. In some cases, small bumps called wheals appear on the skin. These symptoms usually disappear after a few hours or days.
In rare cases, allergy testing can cause an immediate and severe reaction that requires medical attention... For this reason, it is best to perform allergy testing in an office that has the necessary medications and equipment, including epinephrine, to treat anaphylaxis, which is an acute, life-threatening reaction.
If a severe reaction occurs after leaving the office, call your doctor immediately.
Call the emergency department if you experience symptoms of anaphylaxis, such as swelling of the throat, difficulty breathing, fast heart rate, and low blood pressure. Severe anaphylaxis is considered a medical emergency.
After the allergy test
Once your doctor has determined which allergen you are allergic to, you can prepare a plan to prevent its symptoms.. Your doctor can prescribe medications to relieve your symptoms.
