Low-input sample sources, such as cfDNA, are increasingly common in the research and development of potential cancer diagnostic tools. Sequencing analysis of these sample types requires robust methods to confidently detect low frequency alleles. In these cases, unique molecular identifiers (UMIs) may be added to the standard NGS workflow. UMIs offer increased sensitivity in quantitative variant identification where the data may be impacted by confounding PCR duplicates.
