LabCorp Locations At John Muir Health 

As a convenience to our patients, we offer access to lab services through Laboratory Corporation of America (LabCorp) at certain John Muir Health locations. We hope you’ll enjoy the convenience of their services when visiting us, but you’re always free to choose another lab services provider, based on insurance coverage or personal preference. 

For online services related to lab work done at LabCorp—such as scheduling an appointment, viewing your results, or paying your bill online—visit LabCorp.
