Paying for your Diagnostic Tests

If you would like to pay through your medical insurance for your hearing or balance tests, then you will need to obtain a pre-authorisation number from your insurance company before attending the appointment. Simply give them a call quoting our name (Pindrop Hearing or Mr Rony Ganguly), the tests you have been referred for and the name of the referring consultant. Below you will find a list of the most common tests patients are referred to us for, as well as a list of medical insurers and our provider numbers, should you need to quote that as well.

Diagnostic Audiology tests

  • Pure Tone Audiometry with AC BC & Masking – this is a standard hearing test performed through headphones where you will be asked to respond by pressing a button every time you hear a sound. We can modify the test for paediatric patients (see paediatric page)
  • Tympanometry A test of middle ear function to check the middle ear pressure to help in the diagnosis of middle ear conditions such as glue ear or eustachian tube dysfunction.
  • Speech Audiometry This is a test to determine how well you can hear speech at soft levels with and without background noise. You will be asked to repeat sentences presented to you through headphones or through loudspeakers. The volume level will be varied to determine the quietest level you can correctly identify speech (Speech reception threshold) and this will be compared to normal hearing.
  • Paediatric audiology assessment. We use a range of age appropriate methods to test your child’s hearing. For more details please visit our Paediatric Audiology page

Vestibular testing

We provide a full range of tests to measure the balance function in the inner ear for patients suffering with vertigo or imbalance. For full details please visit the balance clinic page.
