Where I live, the doctor/dentist/optometrist never calls me first. They may call me back, but I always call them first. Recently I had some blood tests done and the doctor told me to give them a call in a week. I did, let the receptionist know I was calling about test results and she called me back after getting the details from my doctor. I’ve never got a call from any of them without expecting it because I’ve initiated it.

They sometimes call me to shift appointments. Either something came up for the doctor and they're moving the appointments away, or someone needs a longer very urgent procedure just before my appointment and I'm just going to be there for routine stuff.. things like that.

My spouse is a physician and makes these calls to patients all the time. Might be different in your area but it's been pretty common in the couple states we've lived in.

> Your lab tests came back and we'd like to make a follow-up appointment."

So you're expecting a call from them in this case?

That's typically how it works.
