What is Allergic rhinitis?

Allergic rhinitis is an allergic reaction to environmental allergens. Allergic triggers can include seasonal and/or year-round allergens. Seasonal allergens include grass pollen, tree pollen, weed pollen, and outdoor mold spores.


What are allergic eye conditions?

Allergic conjunctivitis is an allergic reaction to environmental allergens. Common symptoms can include eye itching, burning, tearing, redness, and swelling. Allergic triggers and testing for allergic conjunctivitis are the same as for allergic rhinitis.

What is Asthma?

Asthma is a chronic lung disease that is due to inflammation of the lungs. During an asthma flare the airways become even more swollen and the muscles around the airways tighten. This can cause symptoms including wheezing, coughing, chest tightness, and shortness of breath.

What are possible triggers for asthma?

Asthma can have many triggers, including environmental allergies such as pollen, molds, dust mites, animal dander, and cockroach droppings, irritants such as tobacco smoke and air pollution, as well as viral illness, acid reflux, exercise, cold air, weather changes, anxiety, and stress.

What is food allergy?

Unlike food sensitivities and other food disorders, food allergies are due to your body’s immune system making an antibody, called IgE, to a food. This causes your body to react when you eat the food.

What is eczema?

Eczema or atopic dermatitis is a skin condition that can cause a red, itchy, dry, or scaly rash. This skin condition typically begins in the first few years of life. Common triggers can include stress, heat, humidity, perspiration with exercise, skin infections, irritants.


Skin Prick Testing

Skin prick testing is a form of allergy testing that involves pricks to the skin without the use of needles. Our clinic is able to apply groups of 10 tests at one time with one device, which is designed for more comfortable allergy skin prick testing. A positive test will cause an itchy hive on the skin where the prick was placed. Learn More >>

serum IgE testing

Serum IgE testing is a form of allergy testing that requires a blood draw. IgE is an antibody that your body’s immune system makes to allergens. Learn More >>

Sublingual Immunotherapy

Sublingual immunotherapy is a new FDA approved treatment option for grass and ragweed environmental allergies. An allergy tablet is dissolved under the tongue every day for 5-6 months or year-round in certain cases. This form of allergy treatment has been shown to be clinically effective in well-designed clinical trials. Learn More >>

Subcutaneous Immunotherapy
