Caloric testing
Informed by recognized medical guidance
Overview
Caloric testing is a diagnostic procedure that checks how well your inner ear balance system works. During the test, warm and cool water or air is gently circulated into your ear canal. Your eye movements are measured to see if your balance organs respond correctly. It helps doctors find the cause of dizziness or vertigo.
Key facts
- It is a safe, non‑invasive test that usually takes about 20 to 30 minutes.
- It measures the vestibulo‑ocular reflex, which connects your inner ear to your eye muscles.
- The results help guide treatment for conditions such as vestibular neuritis or Meniere's disease.
Caloric testing is a standard tool used in specialist balance clinics and audiology departments worldwide.
It is used for people of any age who have persistent dizziness, vertigo, or balance problems that have not improved on their own.
