  • Method for quantitatively analyzing tumor cells in a body fluid and test kits suited therefor
    Patent number: 6821726
    Abstract: The invention relates to a method for quantitatively analyzing tumor cells in a body fluid. According to the inventive method, the test sample to be examined is first subjected to a method for accumulating or depleting tumor cells, and a reaction is carried out on the accumulated or depleted tumor cells.
