Overview
We offer full-service, pathologist-directed lab services to help you and your care team better understand your health and care needs.
You must have a physician’s order for any lab tests, but you do not need an appointment. If you have already collected a specimen at home or in your physician's office, you can drop it off for testing.
Please bring your physician order, insurance card and another source of identification (such as a driver’s license) to each visit.
Parking and Transportation
Patients can park in the on-site garage for no cost.
