How should I prepare for my diagnostic procedure?
It all depends on the procedure you’re about to undergo.
Most medical imaging procedures do not require any special preparation. If they do, your referring doctor will have to explain the preparations necessary.
However, if you are at all in doubt, do ask the Marina Hospital staff when you make the appointment. This way, they will be sure to inform you if anything is required on your part before you show up for your appointment.
The most important thing, however, is to remember to bring along your ID, your valid Medicare card and your doctor’s referral.
