Our physicians will combine an in-depth interview, environmental exposure history, and physical examination together with specific laboratory tests to help arrive at a diagnosis. Common allergy tests performed in an allergist’s office include allergen skin testing and spirometry which is a test to measure lung function. One of our allergists will provide individualized treatment plans focusing on environmental avoidance measures and prevention in addition to medical treatment. Allergists are especially recognized for being the expert provider of allergen immunotherapy (allergy shots and sublingual drops). Allergen immunotherapy is the only active intervention that can alleviate allergy or asthma symptoms without the use of medications.

How can you treat allergies once you’ve identified them? We can discuss hygiene and avoidance measures that will decrease the burden posed by the allergen on your body. When these measures aren’t enough, we discuss treatment options with medications, allergy shots and allergy drops. For Patients doing allergy shots, we offer traditional, rush and cluster protocols to build up to the maintenance dose. Most patients, when presented with the options of the various dosing schedules, choose cluster protocol immunotherapy because it offers fewer visits and faster results compared to traditional schedules and a better safety profile than rush schedules.
What is Cluster Immunotherapy (CIT)? Cluster immunotherapy is a method for rapidly desensitizing patients to inhalant allergens. Our cluster protocol involves giving a person multiple allergy injections over several hours over several days, achieving a near-maintenance dose in a very short amount of time. In this way you can do a year's worth of allergy shots in 3-6 weeks! The procedure involves 2-3 rounds of allergy injections, with incremental increases in dose, which are given in a span of 1.5 to 3 hours. After CIT, a person comes into the allergist’s office once a week for the next several weeks. Then we will start spacing out the frequency of your injections according to our immunotherapy (IT) protocol.

What are allergies?
Allergies are the result of your body’s immune system having a heightened sensitivity resulting in reactions to foreign substances that are otherwise harmless. These substances include pollens (trees, grasses and weeds), animal dander and saliva (cats and dogs), mold spores, dust mites, cockroaches, foods, and medications.
Under normal conditions, your immune system would only react if being threatened by harm from pathogens such as bacteria, viruses, fungi, parasites or cancers. However, those who suffer from allergies often experience specific symptoms triggered as your immune system reacts to those harmless substances. Depending on the severity of the allergic reaction, the symptoms can be relatively tolerable or excruciatingly unbearable.
