hi tracy,
welcome to NT. i'm sorry but i can't answer your Q's. i hope someone will come along who can help.
i just moved from denver to fl. fyi
keep going back to the places that did your tests. you should be able to sign a release and not only get the films (maybe on a disc) but a copy of the report.
i hope you'll get some help from your drs. someone needs to coordinate the medical efforts.
