  • Hydrogen Breath Test

    Hydrogen breath test is a test used to diagnose irritable bowel syndrome and common food senstivities, such as lactose intolerance. During the test, a person is given a small amount of fructose, glucose, lactose or lactulose. The person then breathes into a special bag every 15 minutes for three hours and reports any symptoms he or she experiences.
  • Nasal Endoscopy

    Nasal endoscopy is a procedure doctors use to find and examine nasal polyps and anatomical abnormalities in and around the nose. During a nasal endoscopy, the doctor uses a small tube with a light on the end to see inside the nose.
  • Patch Testing

    Patch testing helps doctors find the triggers of allergic reactions. During a patch test, a doctor puts small amounts of suspected irritants or allergens on the patient’s skin to determine which ones are causing flares.
  • Pulmonary Function Testing

    Pulmonary function testing, or spirometry, measures how well the lungs are working. It is used to diagnose and evaluate patients with asthma, cystic fibrosis, lung cancer and other lung conditions.
  • Skin Testing

    Skin testing is a way to diagnose allergies. During a percutaneous skin test, a doctor places a small amount of a suspected allergen on the patient's skin and then pricks the skin with a needle so that the substance seeps under the surface. During an intracutaneous skin test, a doctor injects a small amount of the suspected allergen into the skin. Both types of skin testing help determine which allergens are causing symptoms.
