Also, let your healthcare provider or doctor know of your allergies.

  • Foods

Diagnoses of allergies

Allergies can be diagnosed by:

Personal and medical history 

Allergies can be diagnosed by reviewing your personal and medical history. Your doctor will ask about your symptoms. The things you do, the food you eat and the medications you take that gives you allergic reactions. 

Your family history will also be reviewed. If there is a history of allergic reactions in your family, it is most likely that you will have them too.

Physical exam

 You may undergo physical exams such as x-ray and other physical tests. Skin reactions, eyes, nose, ears, and chest will be observed during the exam.

Allergy Tests

 There are different allergy tests to determine allergens of different individuals. Tests include skin prick test, intradermal skin test, blood test, patch test, and supervised challenge test.

Skin prick test

During this test, your doctor will place a small drop of possible allergen on your skin. Your skin will then be pricked or scratched.

If you are allergic to the substance, you will have skin reactions such as redness, swelling, itching, or irritation within 15 minutes. If there are no skin reactions, that means you are not allergic to the substance.

Intradermal skin test

This test is similar to the skin prick test. However, it is used if the skin prick test shows a negative result but your doctor is not satisfied with the result.

During this test, a small amount of allergen is dropped on your skin without pricking the skin. If there are no skin reactions after some minutes, it indicates a negative result to the allergen.

Blood test or specific igE

A sample of your blood will be taken to the laboratory. An allergen will be added to your blood sample and the amount of antibodies your blood produced to attack the allergen will be measured.

Supervised challenge test

 This test is mostly done for medication or food allergies. During the test, you will need to inhale or swallow a small amount of allergen. You will be supervised by a physician for any allergic reactions.

Patch test

During this test, a small amount of allergen will be placed on your skin and covered with a bandage for 2 to 4 days. If you have a rash or any skin reaction, it indicates that you are allergic to the substance.

Well, the first thing you need to do is find out what you’re allergic to. The most common way to find out is by having a skin test done. This involves nothing more than placing certain substances that you think you might be allergic to on your skin – usually on your back, your upper arm, or your forearm.

Then, the doctor pricks your skin in such a way that the substance that you might be allergic to goes under your skin. Your doctor watches your skin to see if there’s a reaction, like redness or swelling.

Usually if there’s going to be a reaction it will happen in about 20 minutes.


If you’re already taking allergy medications, they could affect the results of the test. The food that you’re eating could also affect the results.

Keep in Mind

Allergy tests aren’t infallible. Allergies are highly flexible, and what you’re allergic to one day might not be what you’re allergic to the next. If you have severe allergies, testing and shots, or even just changing your eating habits may prove to be helpful. Or not.

How Allergy Tests Feel

Following an allergy test, you may find that your nose is stuffy, your eyes water, or your skin turns red if you turn out to be allergic to the substances that are administered in the test. In very rare cases, you may have a full-body reaction, otherwise known as anaphylactic shock. If this happens, and again we have to stress that it is very rare, your doctor will administer cortisone and steroid shots that will alleviate the symptoms.
