Key Points:
- Allergies occur when the immune system reacts to harmless substances
- Allergies can affect various body parts, leading to symptoms such as sneezing, itching, swelling, hives, and anaphylaxis.
- Types of allergy tests are skin tests and blood tests, with skin tests being the preferred method for accuracy.
What are common allergies?
Allergies occur when our immune system mistakenly reacts to a harmless substance. Different allergens, including food, insects, medication, dust, smoke, and animal dander, can cause these reactions. Knowing the various types of allergies is crucial to ensure that we prevent and treat them correctly.
Allergens are substances that cause allergies, including pollen, dust mites, animal dander, certain foods, insect bites, medicines, latex, mold, and household chemicals. usually do not cause any reaction or symptoms in people who are not allergic to them.
What are the symptoms of allergies?

- Severe shortness of breath
- Skin rash
- Lightheadedness
- A rapid, weak pulse
- Nausea and vomiting
What is an allergy test?
Allergy testing is a crucial diagnostic tool that helps identify the specific allergens responsible for triggering allergic reactions. By administering small doses of allergens to patients, allergists can accurately pinpoint the culprits behind the reactions. This information is invaluable in developing an effective allergy treatment plan.
What types of allergy tests are there?
There are two main types of allergy tests:
Skin Tests -There are multiple types of skin tests available to determine allergies. During the first type of skin test, known as a skin prick test, a drop of a suspected allergen is pricked on the surface of the skin. The test is performed on the back of the arm, most commonly the forearm. Many suspected allergens are tested simultaneously. Redness and swelling occur at the test spot if an allergic reaction occurs.
If the results from a skin prick test are unclear, a second type of test may be recommended to rule out false positives. In this type, known as a skin injection test, a small amount of the suspected allergen is injected into the skin of the arm or forearm. Several suspected allergens are tested simultaneously.
Blood Test: Blood tests can be used to determine allergies, although they can produce false positives and are not considered as accurate as skin tests.
