Lab services check-in
If you’re registering for lab services, you’ll still need to stop at your location’s registration desk to check in.
Preregister online at least one full business day before your hospital-based procedure or admission. If there’s less than one full business day before your hospital-based procedure or admission, preregister by phone instead.
We encourage you to use MyChart if you are preregistering for a scheduled appointment. If you are a current MyChart user, most of your insurance information may already be in our system.
