Frequently asked questions
How do I find a good allergist in Nevada?
Look for board certification in Allergy & Immunology, hospital or academic affiliations, and an established practice. Every allergist on this list was vetted against those criteria.
Do I need a referral?
It depends on your insurance plan, not the state. Most PPO plans let you book directly; HMO plans usually require a referral from your primary care physician.
What should I bring to my first appointment?
A list of your symptoms and when they occur, your current medications, your insurance card, and any relevant medical records. A symptom diary matched against local pollen counts is especially useful for diagnosing seasonal allergies.
