The required number of of unique reads for high sensitivity across different cff-DNA concentrations. For aneuploidy detection, the required number of unique reads (y-axis) increased with decreasing cff-DNA concentration (x-axis). For a 3.5% cff-DNA concentration, 1.7 million unique reads are needed to obtain high sensitivity.
