Repository: National Institute of Child Health and Human Development Data and Specimen Hub (NICHD DASH)

Basic Information
Repository Full Name	National Institute of Child Health and Human Development Data and Specimen Hub
Repository Acronym	NICHD DASH
General Theme or Special Population	Children/Youth
Summary	NICHD DASH is a centralized resource for researchers to store and access de-identified data from NICHD-funded research studies for secondary research use. It is a mechanism for NICHD-funded investigators to share research data from studies in accordance with NIH Data Sharing Policies. Many of the NICHD-funded research studies also collected biospecimens that are stored in the NICHD Contracted Biorepository. To provide access to these biospecimens, NICHD DASH stores and make available to other investigators the biospecimen catalog for studies that have associated research data in NICHD DASH. By supporting data and biospecimen access through NICHD DASH, NICHD aims to accelerate scientific findings and improve human health.
