Cell-free DNA (cfDNA) contains potential biomarkers for cancer detection, diagnosis, and progression. Scientists use next-generation sequencing (NGS) to characterize cfDNA. The first step in this process is extracting cfDNA and preparing a sample library. However, cfDNA library preparation must reliably capture and convert all the fragmented DNA within the sample, as attaining low variant detection thresholds and variant calling confidence demands high-performance NGS libraries and targeted sequencing protocols.
