摘　　要：目的验证雅培CD3700血细胞计数仪测定血液白细胞的线性范围。方法用浓缩白膜制备高值白细胞标本，与生理盐水稀释成系列浓度标本，每个浓度测定两次，各浓度的测定顺序随机，对数据进行离群值检验、回归分析和随机误差分析。结果测定结果无离群值，经回归检验在（0-219）×10^9／L范围内为一条通过O点的直线，直线的随机误差在科室制定的批内误差允许范围内。结论CD3700测定血液白细胞的线性范围与厂家声称的基本一致。Objective To verify the linear range of WBC measured by CD3700 hematocyte counter. Methods The high valued specimen was prepared with the enriched white coat,and diluted as a series of concentrations of specimens with the physiological saline. Every specimen was measured for twice,and the sequence of specimens was random. And the Grubbsper test,polynomial regression analysis, and random error estimation were performed. Results There is no outlier in the test results. Re gression analysis showed it displayed linear in the range of 0 to 219 × 10^9/L, and the random error was within the allowable limit of our laboratory. Conclusion The linear range of WBC measured by CD3700 hematocyte counter is coincident to what the manufacturer claims.
