Question 1

Why book through Instalab instead of the facility directly?

Accepted Answer

Booking through Instalab includes what the facility alone does not: the physician order most tests require (no referral or doctor visit needed), scheduling handled for you, and after your visit, an Instalab physician reviews your results, explains them in plain English, and gives you a game plan for what to do next. Your results live in your Instalab account alongside your other tests, so your health picture builds over time instead of sitting in a PDF.

Do I need a doctor's order to book at Longhorn Imaging Center - Onion Creek?
