Calls a medical laboratory in Knoxville, TN 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 Knoxville, TN as much as anywhere.
A few of the calls that come in to medical laboratories in Knoxville, TN:
- A physician's office calls about a specimen status.
- A patient calls to ask whether fasting is required before a blood draw.
- A patient calls to ask about walk-in hours.
Texting patients and providers
Labs use texting mainly for hours, location and preparation reminders.
Because carriers require registration for business texting from local numbers, Callata files a 10DLC registration for a one-time $49; after approval, anyone on the team can reply from the business number.
