Abstract
A method for processing a blood sample is provided that can improve the recovery rate of deformable rare cells that would easily pass through a filter and small rare cells while reducing the filtration area of the filter, and that can recover the rare cells alive.
Claims30
A method for separating or detecting rare cells in a blood sample using a filter including holes with a hole density of 200 holes/mm2 to 40000 holes/mm2, wherein the holes are in the form of an ellipse with a minor axis diameter of 3.0 μm to 15 μm and a major axis diameter of 1.1 times to 3 times as long as the minor axis diameter, or the holes have a shape that contains the ellipse and is in contact with the ellipse on at least two points including both ends of the major axis of the ellipse,
- the method comprising:
- separating or detecting rare cells by filtering the blood sample so that a filter capacity per hole of the filter is 6 μl/hole or less expressed in terms of blood.
