Can't Answer. This is not an answer that can be provided on a format as this. It would be best to contact a local allergist and ask them.
Insurance? Insurance may dramatically effect your out of pocket cost for allergy testing & treatment. With insurance the out of pocket cost can be close to $0. Without insurance there is some variation based on charges set by the provider, and the number of things to which you are allergic. Ballpark figure for maximum is $3500 to $5000 for 3 testing and 3 years of treatment. But you save on future meds.
