Why is my Doctor Bill so High?

Medical tests are excruciatingly expensive. Since the tests were a condition of your employment, is there any chance that the cruise line would reimburse you? If not, then call the lab company and simply ask if there is any way they could give you some relief since you don't have insurance. If not, then they should at least be willing to let you pay over a period of time. It's really up to them. Good luck. And hope you got the job...sounds like you'll need it.
