Any audiologists around? ABR test question

[YogaLite]

Does the cold affect the test? DS due one but has a heavy cold.
I can't find specific info online about ABR, only about standard tests (which would definitely be affected).

Yes - having a cold/nasal congestion may/can affect ABR test results - just like if you were to have a standard hearing test and had a cold/flu at the same time. It if is a recent thing, I would see if you could reschedule the ABR for a week or so, until DS has recovered.

Thank you for this @deyhuggy I have been trying to contact the hospital to check but so far unsuccessfully ...
