Quest Diagnostics in Great Falls is a professional facility offering routine lab tests, drug screens, and COVID-19 antibody testing by appointment. It is located in the Prospect Heights medical building next to Benefis West Hospital, with easy-to-find, ample parking. Check-in is a breeze and the lab personnel are described as professional, friendly, and caring. Many report a fast, easy experience with little to no wait. However, phone communications receive criticism for long automated hold times, though in-person service is consistently praised. Patients appreciate the online access to easy-to-read lab reports going back many years.
Last time I was there they had 1 person working and I waited over an hour and fin a lly left. Was not aware you needed an appointment and I don't think it would have made a difference.

If you order through Ulta Health, you get a tremendous discount. Quest is very well run with excellent staff. I got my results in one day.
