Abstract excerpt
BACKGROUND: Detection of somatic genomic alterations in tumor-derived cell-free DNA (cfDNA) in the plasma is challenging owing to the low concentrations of cfDNA, variable detection methods, and complex workflows. Moreover, no proper quality control materials are available currently. METHODS: We developed a set of synthetic cfDNA quality control materials (SCQCMs) containing spike-in cfDNA on the basis of...
