Team sizes at medical laboratories in Delaware
92.1% of Delaware's medical laboratories with employees had fewer than five people in March 2023, compared with 69.4% nationally. 100.0% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.
| Employment size | Establishments | Share | U.S. share |
|---|---|---|---|
| 1–4 employees | 58 | 92.1% | 69.4% |
| 5–9 employees | 5 | 7.9% | 13.6% |
| 10–19 employees | not published | — | 7.5% |
| 20–49 employees | not published | — | 4.8% |
| 50 or more employees | 0 | 0.0% | 4.6% |

What medical laboratories in Delaware 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.
Calls a medical laboratory in Delaware might handle in a typical week include:
- A patient calls to ask about walk-in hours.
- A courier calls to confirm a pickup.
- A provider calls to add a test to an existing order.
Texting patients and providers
Labs use texting mainly for hours, location and preparation reminders.
Texting from a local number in Delaware requires carrier registration (10DLC), a one-time $49 fee on Callata.
Phone system pricing for a 4-person medical laboratory
Medical laboratories in Delaware average 3.8 employees, so the comparison uses a 4-person team. Priced per seat, 4 users would run $120.00 a month on RingCentral RingEX Core and $99.80 on Ooma Office Pro (month-to-month list prices, checked September 28, 2026). Callata comes to $99.00 a month for 4 users ($99 a month with 5 users included, then $20 per additional user), below both.
Over a year, that is $252 less than RingCentral for a medical laboratory in Delaware of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.

How Callata works for medical laboratories in Delaware
Callata Office costs $99 per month for up to 5 people, and each additional user is $20 a month. That covers up to 3 local numbers, calling from a browser or your cell, transcribed voicemail, recorded calls with AI summaries, after-hours routing and E911 on each number.
Porting a number you already use in Delaware is free, and business texting is available once the carrier registration (10DLC) is approved; the registration carries a one-time $49 fee. Which specific numbers are open in a given area code depends on carrier inventory at the time you sign up.
AI agents are optional: an AI receptionist or scheduler can pick up when the team is busy or closed, take a message, send a text or email, or transfer the call. They draw on prepaid AI minutes ($0.25/minute), disclose that they are AI, and outbound AI calls require prior consent and are limited to 8am–9pm.
Practices that handle protected health information should review their own privacy obligations before recording calls, enabling AI summaries or texting appointment details, and keep clinical conversations out of text messages unless their policies allow it.
