Get In and Out Faster –
Make an Appointment for Your Next Lab Visit
Need a lab test and pressed for time? Not a problem! Our new Laboratory by Appointment service will get you in and out of the lab as quickly as possible.
Ask your doctor’s nurse to preschedule your lab appointment – or do it yourself if you’re enrolled in MyKelseyOnline, our secure online patient portal.
It’s easy:
Log in to
MyKelseyOnline and select "Make Your Own Appointment" and then "Lab Appointment."
- The system will walk you through making a lab appointment.
- Choose from a menu of available time slots at any location.
- You will receive an email reminder prior to your scheduled time. When you arrive for your appointment, you’ll be called ahead of all same-day walk-ins. We recommend you bring a copy of your medical insurance card to expedite your visit.
Appointments are not required. However, patients with a lab appointment are given priority (except for urgent or emergency cases). Patients without appointments are seen in the order of arrival.
If you choose not to make an appointment, please note that our labs are busiest in the early morning when patients who are required to fast for testing often choose to arrive. Wait times are usually shorter after 10 a.m.
We know your time is valuable, so our objective is to get you in and on your way as quickly as possible.
