What is Allergy?

Allergy is a hypersensitivity caused by exposure to a particular allergen resulting in a reaction. This site is primarily concerned with upper respiratory allergies. These allergies affect the nose, nasal passages, sinuses and lungs. They can lead to other diseases such as sinusitis or can affect your asthma.

Testing can help determine the presence of allergy and/or other pathology.
