Sample Processing Core Laboratories

Due to the ongoing United Auto Workers (UAW) strike, studies requiring United Parcel Services (UPS) shipments have been impacted since November 14th. UPS has indicated their drivers will not cross the picket line and have halted the pick-up and delivery of packages from all UCSF campuses. The duration of the strike currently remains unknown. Frozen samples will be stored safely onsite until further notice. Study teams should be prepared to make alternate arrangements for same-day sample shipments.

For more information, please contact Ron Honrada at [email protected].

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.
