Welcome to the UCSF Viral Diagnostics and Discovery Center (VDDC) and Chiu Laboratory at UCSF China Basin! The UCSF VDDC is a core facility for viral diagnostics arising from a multi-year collaborative agreement between UCSF and Abbott Laboratories.

Precision Diagnosis of Acute Infectious Diseases (PDAID)

Current tests in clinical microbiology fail to diagnose many life-threatening infections in a timely fashion, resulting in increased health care costs and likelihood of death. At UCSF, we have developed and clinically validated a metagenomic next-generation sequencing (mNGS) assay to reveal the cause of unknown infections that commonly elude physicians. This is a "needle-in-a-haystack" approach that allows us to identify all potential pathogens -- viruses, bacteria, fungi, and parasites -- in a single sequencing test. Powered by SURPI for computational analysis, we have as of June 2016 completed clinical laboratory validation of this assay for diagnosis of encephalitis and meningitis from cerebrospinal fluid (CSF). From June 2016 to June 2017, we will enroll and sequence CSF from 300 hospitalized patients in a prospective multi-center study to evaluate the clinical utility and cost-effectiveness of this mNGS laboratory-developed test.

Collaborators on the PDAID study (PI Chiu) include UC Davis, UCLA, Children's Hospital Colorado, Children's Hospital Los Angeles, Children's National Medical Center, St. Jude's Children Research Hospital, UC Berkeley, DNAnexus, Syapse, Google, Quest Diagnostics, Illumina, and the California Department of Public Health. This study is funded by the California Initiative to Advance Precision Medicine and philanthropic grants from the Sandler, Bowes, and Schwab Foundations.
