What Are Calorics?
A Diagnostic Test for Balance & Vestibular Function
Calorics (also known as the Caloric Reflex Test) are a non-invasive diagnostic procedure used to assess the function of each inner ear’s vestibular system — the part of the ear responsible for balance.
The test works by introducing warm or cool air (or water) into the ear canal to stimulate the horizontal semicircular canal, which triggers eye movements (nystagmus) that help clinicians evaluate the health of your balance organ.
In our clinic setting, this assessment is offered for patients who experience dizziness, vertigo, imbalance, or other sensations of instability that may be linked to inner-ear or vestibular disorders.

Who It’s For?
Recommended for Patients Experiencing Balance or Dizziness Issues
This service is ideal for individuals who:
- Frequently feel dizzy, lightheaded or off-balance
- Have experienced vertigo, spinning sensations or unexplained falls
- Are being evaluated for vestibular disorders such as Meniere’s disease, vestibular neuritis or labyrinthitis
- Want to understand the root cause of balance issues before proceeding with treatment
If you suspect you have an inner-ear or brainstem condition, it’s best to first speak with your healthcare provider or a specialist in vestibular disorders.
What’s Included?
Detailed Vestibular Assessment in a Comfortable Setting
Our calorics service includes:
A preliminary examination of your ears/tympanic membranes to confirm suitability for the test (important if there is any perforation).
he application of warm or cool air (or occasionally water) into each ear canal while you lie quietly, head elevated at approximately 30°.
Continuous monitoring of eye movements (nystagmus) and balance responses, often via video goggles or electrode systems.
A report of findings and discussion of results with a vestibular-trained clinician, with potential next-step recommendations.
Benefits of Calorics Testing

Safety & Considerations
Calorics are generally safe when performed by trained specialists. Minor dizziness, nausea or eye-motion may be experienced during the test, but these effects are temporary and monitored.
Important considerations: The ear-drum (tympanic membrane) must be intact for the water version of the test; if not, air stimulation is used. harleystreetent.com Some medications, caffeine, alcohol or sedatives may affect results; you may be asked to avoid them prior to testing.
If you have known labyrinthitis, recent ear infection or other acute vestibular issues, your clinician will advise you accordingly.
