The authors studied the changes in the percentage of reticulocytes in blood preserved for three weeks. The samples were obtained from healthy adults and stored at 4 degrees C. An automated reticulocyte counter was used for measurements. After one week, the relative percentage of reticulocytes had decreased to around 80% of the initial value, and it reached 60% after three weeks of storage. When the y-axis of plots of the change against time was converted to a log scale, negative correlation was strong (r = -0.9972), and the curve was useful for estimation of the reticulocyte count in preserved blood. Stored blood might be used as a control material for reticulocyte counting by automated methods.
作者研究了保存三周的血液中网织红细胞百分比的变化。样本取自健康成年人，并在4摄氏度下储存。使用自动网织红细胞计数器进行测量。一周后，网织红细胞的相对百分比降至初始值的约80%，储存三周后降至60%。当将随时间变化的曲线的y轴转换为对数刻度时，负相关性很强（r = -0.9972），并且该曲线可用于估计保存血液中的网织红细胞计数。储存的血液可作为自动方法进行网织红细胞计数的对照材料。
