- Can I book an appointment directly or do I absolutely need a referral?

This ensures continuity of care and that the consultation is appropriate for your needs. Please have your doctor forward the referral information.

- Referrals are typically appropriate for adults with complex diagnostic challenges, poorly controlled chronic diseases (like advanced Syncope (Fainting) Evaluation or Chronic Respiratory Diseases), multiple interacting medical conditions, or unexplained symptoms.

Your family doctor can best determine if a specialist consultation is needed.
- What typically happens during a first consultation?
- During your initial visit, Dr. Yin will conduct a thorough review of your medical history, symptoms, and medications based on your referral and the information you provide. She will likely perform a relevant physical examination.

There will be time for you to ask questions.
