What medical laboratories in Chicago, IL-IN use the phone for
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.
Typical inbound and outbound calls for medical laboratories in Chicago, IL-IN:
- A courier calls to confirm a pickup.
- A provider calls to add a test to an existing order.
- A patient calls to ask whether fasting is required before a blood draw.
When nobody can pick up
After-hours calls are mostly about the next day's hours and preparation, which a clear greeting can answer.
