Clinical Immunology

Allergic conditions affect up to 30% of the population and can have a significant impact on the quality of life of affected patients.

Airborne allergies can have a significant impact on both the upper and lower respiratory tract, causing the familiar seasonal or year-round itchy, watery eyes, runny nose, sneezing and nasal congestion, and asthma with coughing, wheezing, and shortness of breath. Identifying the allergens that are contributing to patients' symptoms can allow the introduction of measures to reduce exposure to these allergens and improve health and well-being. This may reduce the need for medications, but if medications are required, the use of medications can specifically targeted to periods of exposure, in some cases.

Many patients with respiratory allergies have other allergy-related problems, such as food allergy or eczema. A separate area is that of medication allergies, or other adverse reactions to medications.

Disorders of the immune system are less common than allergic conditions, but can negatively impact respiratory health. Currently, evaluations are available off-site, but will become available on site in the near future.

We offer on-site consultations and testing for allergic or other adverse reactions to medications upon the appropriate referral at the Drug Safety Clinic. Evaluation for respiratory and other allergic problems are currently available off-site at 30 St. Clair Avenue West, Suite 204.
