Abstract PreVAIL-kIds sites have iden5fied opportuni5es to rapidly acquire and share samples and clinical data among themselves, thus catalyzing the process of mul5-site valida5on of their ongoing developmental assays and algorithms. Via a survey conducted in April 2023, the sites have iden5fied the matrix of shareable/usable samples and data amongst members of the network. Over 80% of possible exchanges are going to be frui8ul. The goal of this supplemental applica5on is therefore to facilitate the rapid exchange of data/samples between the 8 PreVAIL-kIds sites, so that mul5-site valida5on of their respec5ve assays and algorithms can proceed.
