A referral to an allergist if you are going private. It cost around $280 for the initial appointment with all the skin testing as well. It was very long appt. As you see the specialist, then usually wait for the nurse for the testing and then have to wait for the reaction (they do quite a few on the back if they are little) and then back to the nurse and then back to the specialist all in one go. So allow a good couple of hours.
If you go public, you could have a long wait depending on the severity of the allergy and how the GP or dietitian wrote the referral.
Some specialists ask you to fax the referral first then will call you to make an appointment so they can determine how urgently you need to see them.
It can take up to 6mths sometimes longer to see these rare as hens teeth paediatric allergists.
