Allergy Testing & Treatments
Comprehensive testing and treatment designed around you.
Prick to Prick Test
Rhinolight Therapy
Rhinolight therapy is a pain-free and effective way to ease allergy symptoms like a stuffy, blocked, or runny nose.
Rhinomanometry
Rhinomanometry is a non-invasive test that measures how easily air flows through your nose when you breathe. It helps doctors assess nasal airway resistance, which means how much effort it takes to breathe through your nose. Think of it as a way to check if your nose is functioning like a clear tunnel—or if it’s more like a narrow, blocked pipe.
Skin Prick Testing
Skin Prick Testing (SPT) is a simple, non-invasive way of testing for allergies on the skin. Results are available after 15 minutes.
Spirometry
Tympanometry
