I'm not usually one for forwarding those mails you get about Bill Gates needing to test his email system or the kid in the UK who needs postcards, but this one, forwarded by a friend, appears to be legitimate. The hospital exists, and so does the domain for the original sender (which I have modified slightly, but humans should be able to figure it out):
