Circulating tumor cell (CTC) count using the On‐chip Sort system compared with the CellSearch system. (A) CTC count/7.5 mL blood is shown for 10 healthy donors and 30 patients with non‐small‐cell lung carcinoma (NSCLC). Paired blood samples were analyzed by CellSearch according to the manufacturer's protocol and On‐chip Sort by immunolabeling analysis. (B) Direct comparison of CTC counts between CellSearch and On‐chip Sort. Gray line represents the theoretical perfect correlation. The cut‐off levels (3 CTCs for On‐chip Sort and 2 CTCs for CellSearch per sample) are indicated by the dashed lines
