The reason you don't get your test results over the phone is that it is not the doctor who is phoning you, usually it is the receptionist. By law only physician's are permitted to tell you test results because they have to be interpretted in light of your medical condition and history. Medical receptionist might know some stuff, but not at that level. Besides, how many of you have actually had a physician phone your home

Good luck with the test results. I am sure that it is nothing serious.
