Give them a call, the results may be in, and if you can move up your appt? All they can say is, no.
Often, at a large hospital, doctor offices, testing department or labs, I wouid go to the records department or offices, and obtain copies of surgeries, tests, results before seeing the doctor, sometimes days or weeks ahead. Only once I was denied, when a speech pathologist saw me, and inquired about my visit, so they didn't give me any copies while the dr was on vacation. This is only if you can take seeing the results yourself, and able to understand some of the results, which is usually explained in the Findings or Interpetation.
I hope this helps
