Allergy Testing

Allergy Testing

At Affiliated Dermatology, we provide options for allergy assessment and treatment to address symptoms associated with allergies and skin sensitivities. We address a vast number of food and airborne allergens, such as seasonal allergies, hay fever, eczema, rashes, blisters, hives, pet hair and animal dander, pollens, dust and much more. 

Some tests detect immediate allergic reactions, which develop within minutes of exposure to an allergen while other tests detect delayed allergic reactions, which develop over a period of several days.

Allergy Skin Patch Testing

Skin Patch Testing

Patch testing is generally done to see whether a particular substance is causing allergic skin irritation (contact dermatitis). Patch tests can detect delayed allergic reactions, which can take several days to develop.

Patch tests don't use needles. Instead, allergens are applied to patches, which are then placed on your skin. During a patch test, the skin on your back may be exposed to up to 36 extracts of substances that can cause contact dermatitis. These can include latex, medications, fragrances, preservatives, hair dyes, metals, chemicals and resins. Patch tests are performed over a 4 day period with most results being seen in 72 hours. 

During this time, you should avoid bathing and activities that cause heavy sweating. The patches are removed when you return to Affiliated Dermatology. Irritated skin at the patch site may indicate an allergy. Affiliated Dermatology also offers a skin test on the back with 80 antigens that provides results within 60 minutes.

Asthma Testing

Allergy tests are a way to get to the bottom of what's causing your asthma symptoms as they help your practitioner determine if allergies trigger your asthma. Many people with asthma are allergic to tiny particles (allergens) that they breathe in. Examples of airborne allergens are the pollens of grasses, trees, and weeds, spores of molds, danders of cats and dogs and other furry animals, and dust mites. Day to day inhalation of allergens to which you are sensitive can worsen the inflammation of the bronchial tubes in asthma. Additionally, it can cause your asthma to become more active (meaning that you are more likely to be troubled by cough, wheeze, shortness of breath, chest tightness, or nighttime awakenings from asthma symptoms) and make you more likely to have a serious attack of asthma.


Asthma Allergy Testing

Xolair Allergy


XOLAIR® is a popular injectable allergic asthma drug. The antibody helps decrease allergic responses in the body and is used to treat moderate to severe asthma that is caused by allergies in adults and children who are at least 12 years old. It is not a rescue medicine for treating an asthma attack. Additionally, prescription XOLAIR has been shown to significantly reduce the itch of hives as well as number of hives for chronic idiopathic urticaria (CIU) patients uncontrolled on H1 antihistamine treatment.

Allergy Injections

You may need an allergy test that uses a needle to inject a small amount of allergen extract into the skin on your arm (intradermal test). The injection site is examined after about 15 minutes for signs of an allergic reaction. Your dermatologist may recommend this test to check for an allergy to insect venom or penicillin.

Allergy Injections

Your allergy treatment plan may include medications, immunotherapy, changes to your work or home environment, or dietary changes. Ask your doctor to explain anything about your diagnosis or treatment that you don't understand. With test results that identify your allergens and a treatment plan to help you take control, you'll be able to reduce or eliminate allergy signs and symptoms.
