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.
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.
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.
