Marin General Hospital: Outpatient Laboratories

Marin General Hospital offers a professional, caring, community-based network of laboratories throughout Marin County. We have four outpatient laboratories- one located in Greenbrae, one in Larkspur, one in Mill Valley, and one in Novato. We encourage patients to use our outpatient laboratories for convenience and ease of registration and parking.
