Abstract
A leukocyte measurement device is provided with a spread inspection window at a position separated from an opening part along a spreading direction of a blood-derived sample in a carrier, for making the carrier visible from outside. When the blood-derived sample is dropped from the opening part, leukocytes contained in the blood-derived sample are captured by the carrier in the vicinity of a dropping position, while erythrocytes and/or hemoglobin and the like spread through the carrier from the dropping position into a predetermined direction. Therefore, in the leukocyte measurement device, seeing through the spread inspection window the color of the erythrocytes and/or hemoglobin spread from the dropping position can determine whether it has already been used or not, whereby a simple structure can prevent measurers from erroneously reusing it.
