Figure 4. Precision, accuracy, and validity of the CellSearch®-PSMA assay.
Blood from one donor was used, and transferred into CellSave® preservation tubes. Cells of the LNCaP line were spiked into blood by dilution series. Two samples were processed in parallel at day one (samples 1_1 to 1_2) in the same batch / run and two samples (2_4 and 2_5) were processed at day two. Samples 2_4 and 2_5 were stored at room temperature until analysis.
