Diamond Bar CA Allergy Testing, Immunologist & Sinus Doctor
GERIATRICS & GERONTOLOGY DIAMOND BAR CA
Dr. Rafi and his team at the Allergy, Asthma, and Sinus Institute specialize in helping older patients. Dr. Rafi finished a one-year program in older people’s health at UCLA and an advanced older people’s program. He focused on boosting the immune system and staying healthy as you age.
Our older patients are usually over 65, but it’s not just about your age. You could be 70 years old, working five days a week, and still not be considered older. Or you could be 60 years old with several health problems, taking many medicines, and fall into the older category. How well can you do things at home and outside? What health issues do you have? And how complicated is your medical history?
With each new patient, we start from the beginning. We usually begin by looking at the medicines you’re taking and your recent test results. Then we may do more tests if needed.

Dr Asif Rafi
What you can expect on your first visit:
Your first visit to Dr. Rafi is very comprehensive. We take your history to learn all aspects of your condition and perform an initial examination. Most likely, we will perform skin testing during this visit. It might be skin testing for classic allergies or patch testing for allergic contact dermatitis. We also test for exhaled nitric oxide (called FeNO) to determine the level of allergic inflammation in your lungs. We offer spirometry for assessment of lung function. We can perform nasal endoscopy with a flexible fiber optic endoscopy to assess for nasalpolyps, deviated septum, and candidiasis.
