Your primary care physician will refer you to a lab and submit the order directly to the lab or provide you with paperwork to bring with you.

If your physician has submitted your laboratory orders electronically, your results should appear in your MyChart account. All other patients should check with their physician regarding their lab results.

We will help you during this transition.

If you have questions, you can ask your physician or one of our laboratory caregivers. In addition, a call-in number (707-525-5270) will be active starting March 18, where members of the community can get questions answered.
