摘要
目的分离血小板验证Bayer ADVIA 2120全自动血细胞分析仪的血小板线性范围。方法按IS015189的EP6-A要求，从250份样本中分离血小板对血小板线性范围进行验证。结果任意混合多样本分离血小板取得高浓度血小板，Bayer ADVIA 2120检测血小板批内和天间不精密度为3．0％和3．6％，携带污染率为0．02％，血小板在21～4918×10^9／L范围内呈一项次线性关系。结论可不分血型混合血浆，通过分离、浓缩取得高浓度血小板；Bayer ADVIA 2120全自动血细胞分析仪检测血小板精密，线性良好，线性范围宽，携带污染率低，是一台检测血小板性能良好的全自动血细胞分析仪。
Objective To verify the linear range of the platelets at Bayer ADVIA 2120 analyzer. Methoils According to ISO15189 EP6-A, platelet separated from 250 samples to verify the linear range at Bayer ADVIA 2120 analyzer. Results High eoneentrations of platelet can obtained from mixing multi samples. Coefficient of Varianee of within-run and between-day was 3.0% and 3.6% ,earry-over was 0. 02% ,platelet range at 21- 4918 × 109/L Showed a linear relationship. Conclusion Regardless of blood type, high concentrations of platelet can obtained from mixing multi samples. Bayer ADVIA 2120 automated hematology analyzer has good feafures of precision, linearity, low carry-over,is a perfect performance analyzer.
