If this was in the last 5 years from the date of the medical application you will need to produce the documents. If you blew .15 or more or refused to blow you will be kicked up to the FAA for a decision. If this happens you should get an AME that knows what he is doing in this situation as one who does not can really drag out the process.
Sorry if that was not the side of this you wanted info on. Be careful about counting on a medical certificate that you do not have in your hands, it has cost others considerable money.
