Figure 3. Sensitivity and specificity of patient-specific amplicon-sequencing assays for detection of ctDNA in plasma.

Figure 3

Plasma from 6 patients (labelled A–E) and 3 healthy volunteers (H1,H4,H5) were assayed for ctDNA using 6 different patient-specific primer sets (labelled A–F). Primer set labels match that of the patient they were designed for. Plasma from volunteer H1 was taken from a later timepoint (H1B) and re-tested with the same primer set F. This sample H1B was not used for calculations of sensitivity and specificity.
