Sample Processing Core Laboratories

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.

Please contact [email protected] 14 business days prior to opening a study.  A speedtype is required in order to provide services but we can assign a study ID and review materials in advance of final documents.
