A method for treating a blood specimen with which capture rates for both a small rare cell and a rare cell having high deformability can be improved in the case where rare cells are contained in a blood specimen. The method for isolating or detecting a rare cell includes treating a blood specimen using a filter to isolate or detect a rare cell in the blood specimen, the filter including holes having a minor axis diameter of 5 to 8 µm and a major axis diameter of 40 µm or more at a hole density of 40 to 2000 holes/mm 2 with the ratio (w/z) between the major axis diameter w (µm) and a gap z (µm) between the holes in the minor axis diameter direction being 7.0 to 130. |
