Sample Processing Core Laboratories

Due to the COVID-19 Pandemic, CRS operational hours have changed: Sample processing laboratories will be accepting and processing samples for essential studies only.

The CRS Sample Processing Core Laboratories perform specimen processing, sample storage, and shipping for a wide variety of clinical trials. Our services are available to all UCSF faculty, residents, research fellows, and collaborators who complete a CRS application and have an IRB approved protocol. Laboratory staff members are also available for custom assays and for consultation on budget inquiries.
