As of November 26, 2018, Marin General Hospital has sold its outreach laboratory services to Quest Diagnostics and the 4 off-campus labs we operated previously (Greenbrae, Larkspur, Mill Valley, and Novato) are now Quest Patient Service Centers.

Our in-hospital lab is open and is available for lab draws and specimen collection for patients who need them related to other hospital services they are receiving during the same visit, like imaging or surgery. The lab is located in the hospital on Floor 2 in the East Wing.
