Calls a medical laboratory in Riverside, CA has to catch
Labs answer calls from both patients and ordering providers, and the questions differ: hours and preparation instructions on one side, specimen and result status on the other. Routing those calls separately keeps both groups from waiting. That holds for medical laboratories in Riverside, CA as much as anywhere.
Calls a medical laboratory in Riverside, CA might handle in a typical week include:
- A provider calls to add a test to an existing order.
- A physician's office calls about a specimen status.
- A patient calls to ask about walk-in hours.
When nobody can pick up
After-hours calls are mostly about the next day's hours and preparation, which a clear greeting can answer.
Callata transcribes voicemail and triages it for urgency, so the first callback in the morning can go to the caller who needs it most.
