Comprehensive Guide to Diagnostic Techniques for Allergic Conditions
Allergy tests are a set of diagnostic procedures used to identify specific allergens that may be causing allergic reactions in an individual. Allergic reactions appear when the immune system overreacts to a substance that it finds as harmful, even if it may be harmless.
Common allergy tests include skin prick tests, blood tests, patch tests, oral food challenges, and elimination diets. These tests can help to diagnose a range of allergic conditions, including food, environmental, and skin allergies such as eczema.
Allergy blood tests are usually ordered by a healthcare provider when a person has symptoms that suggest an allergic reaction, such as sneezing, coughing, itchy eyes, and skin rashes. The test results can help identify the specific allergens that trigger the allergic reaction, allowing more targeted treatment and management strategies.

There are different types of allergy blood tests available in Phoenix, including:
- ImmunoCAP test: This is a specific IgE blood test that measures the levels of allergen-specific IgE antibodies in the blood.
- RAST test: This is a radioallergosorbent test that measures the levels of allergen-specific IgE antibodies in the blood.
- ELISA test: This is an enzyme-linked immunosorbent assay that measures the levels of allergen-specific IgE antibodies in the blood.
Some of the other Common Allergy Tests or Procedures are as follows:
1. Skin prick test
A skin prick test is a commonly used test for diagnosing allergic reactions. It requires placing a small amount of allergen on the surface of your skin and then scratching or pricking the skin to allow the allergen to enter the body.
2. Patch test
A patch test is used to diagnose delayed-type allergic reactions, such as contact dermatitis. A small amount of allergen is applied to a patch, which is then placed on the skin for a period of time. If a reaction occurs, it indicates that the person is allergic to the substance.
3. Oral food challenge
An oral food challenge involves giving a person a small amount of a suspected allergen to eat and monitoring them for symptoms of an allergic reaction.
4. Nasal provocation test
A nasal provocation test is used to diagnose allergies to airborne allergens such as pollen, dust mites, or animal dander. It involves inhaling small amounts of the allergen to provoke a reaction.
5. Elimination of diet
An elimination diet involves removing certain foods from a person’s diet to see if their symptoms improve. If the symptoms do improve, it may indicate that the person is allergic to one or more of the eliminated foods.
It’s important to note that you will need a referral from a healthcare provider to get allergy blood testing done at most medical facilities. Your primary care doctor or an allergist can provide you with a referral for it and help you choose a facility that is best suited to your needs.
