Patients undergoing an elective procedure will need to have a COVID-19 test done 4-6 business days before their procedure. For your convenience, we opened a curbside COVID-19 Pre-Procedural Testing Center where you can have the test performed from your car The Center is located at N. Broadway and 8th Ave. N outside near SameDay Care. Your care team will schedule a time for you to have your test done at the Center. Testing samples are sent to Mayo Clinic for analysis and take about four to six business days for results. Patients will need to self-quarantine for the period of time between the test sample being collected and the date of their procedure. Thank you for taking this important step to protect yourself, our care team, and other patients.

This Center is specifically for patients scheduled for a procedure who do not have symptoms of COVID-19. Symptomatic patients can call Healthline at (406) 255-8400 or 1-800-252-1246.
