ABSTRACT:
A method for determining the concentration of vital epithelial tumor cells in a body fluid is disclosed. The method comprises obtaining from the body fluid of a test subject a test specimen, labeling the epithelial tumor cells contained in said test specimen, applying the test specimen to a support, where the epithelial tumor cells adhere and identifying vital cells of the adhering epithelial tumor cells by means of their morphology. The method does not comprise an enrichment of epithelial tumor cells by means of binding to paramagnetic or magnetic particles and applying a magnetic force to the particles.
