At our Houston clinic, our board-certified allergist-immunologists begin the evaluation with a comprehensive history and physical examination. We may conduct skin testing for environmental and food allergens, spirometry to assess lung function, and, if necessary, endoscope examination of the nose and postnasal areas. To ensure efficiency, all relevant and safe tests are performed on the same day. In certain cases, specialized procedures may require scheduling for a later date. After completing the evaluations, we discuss the findings and may order blood tests to examine your immune system, CT scans of sinuses or lungs, and other tests. Together, we develop a personalized management plan to improve your health, which may include allergen immunotherapy (allergy shots) for environmental allergies.
