The CellSearch™ Circulating Tumor Cell kit is intended for the quantification of circulating tumor cells (CTC) of epithelial origin for metastatic breast, colon, or prostate cancer, in whole blood. This assay can be used to predict progression free and overall survival in patients treated for metastatic cancer.
The results of a CellSearch test should be interpreted with caution if specimens are drawn within 7 days of administration of doxorubicin therapy.
