YES, an individual has a legal right to his/her medical records.
The doctor may (by law)charge a nominal copying fee and may make you jump through a couple of hoops (sign forms, wait a week, etc.) In the end though, those records are yours.
Some docs are better than others. I am in the process of gathering all mine and at one office I was handed a thick stack neatly stapled in an envelope with my name on it. In another, I was looked at as if I was an alien requesting everyone's firstborn child for experimentation and handed exactly one piece of paper. I patiently explained to the nurse that I wanted it ALL. She was not pleased, but I did get them.
Just tell your friend to be firm, persistent, polite, and that those records are HIS/HERS!!!
