(57) [Summary] [Object] To provide a means capable of measuring reticulocytes with high sensitivity, accuracy, and at low cost by using a dye that is convenient for staining reticulocytes. [Structure] TOTO-3 or TO-PR as fluorescent dye O-3, POPO-3 or PO-PRO-3, YOYO -1, or YO-PRO-1, or YOYO-3 or Y For a blood sample stained with a fluorescent staining solution containing O-PRO-3, TOTO-3 or TO-PRO-3 is red, POPO-3 or PO-PRO-3 is green, and YO. Blue for YO-1 or YO-PRO-1, YOYO-3 Alternatively, in YO-PRO-3, reticulocytes are measured by irradiating light in the orange wavelength region and measuring the fluorescence from the blood sample. |
