Calls a medical laboratory in San Jose, 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.
A few of the calls that come in to medical laboratories in San Jose, CA:
- A patient calls to ask about walk-in hours.
- A patient calls to ask whether fasting is required before a blood draw.
- A physician's office calls about a specimen status.
Business texting for medical laboratories
Labs use texting mainly for hours, location and preparation reminders.
Team texting on Callata runs from your business number, so replies come from the practice or shop rather than someone's personal phone. It turns on after the one-time $49 carrier registration (10DLC) is approved.
