摘要: 目的

探讨PL-11血小板分析仪在检测血小板数量及聚集功能方面的性能。

方法

按照美国临床实验室标准化协会(CLSI) 制定的仪器性能验证标准及我国卫生行业标准 WS/T 406-2012《临床血液学检验常规项目分析质量要求》对PL-11血小板分析仪进行血小板计数及聚集功能的性能评价。采用PL-11血小板分析仪、LBY-NJ4血小板聚集仪及TEG-5000血栓弹力图仪检测健康人群血小板聚集率,分析各仪器检测结果间的相关性。

结果

PL-11血小板分析仪的批内及日间精密度均<1/3总误差(7%);携带污染率为0.32%;在(4.12~1 380.4)×109/L线性范围内回归方程斜率为 1.03,R2=0.993;血小板计数结果与血小板参考方法的结果符合率为84%,均符合行业标准要求。分别采用PL-11血小板分析仪、LBY-NJ4血小板聚集仪及TEG-5000血栓弹力图仪检测79例2型糖尿病患者单服用氯匹格雷前、后血小板聚集率,3种仪器之间差异均无统计学意义(P>0.05),患者服药前、后血小板聚集率差异有统计学意义(P<0.01)。

结论

PL-11血小板分析仪可为临床提供准确、可靠的血小板计数及聚集功能的检测结果。

Abstract: Objective

To investigate the performance of PL-11 platelet analyzer in the detection of platelet count and platelet aggregation.

Methods

According to the instrument performance verification standards in the Clinical and Laboratory Standards Institute (CLSI) and the Health Industry Standard of the People's Republic of China, WS/T 406-2012: the Quality Standard of Routine Tests in Clinical Hematology, the performance of PL-11 platelet analyzer in the detection of platelet count and platelet aggregation were evaluated. Platelet aggregation rate in healthy subjects was compared for correlation, which was detected by PL-11 platelet analyzer, LBY-NJ4 platelet tester and TEG-5000 thromboelastogram.

Results

The within-run and inter-day precisions of PL-11 platelet analyzer were<1/3 of total error (7%), and the carry-over rate was 0.32%. In (4.12-1 380.4)×109/L linear range, the regression equation slope was 1.03 (R2=0.993). The coincidence rate for platelet count by PL-11 platelet analyzer with reference method was 84%. There was no statistical significance of platelet aggregation rate among PL-11 platelet analyzer, LBY-NJ4 platelet tester and TEG-5000 thromboelastogram in 79 patients with type 2 diabetes mellitus (P>0.05). However, there was statistical significance in platelet aggregation rates before and after taking clopidogrel hydrogen(P<0.01).

Conclusions

PL-11 platelet analyzer can provide accurate and reliable results for platelet count and aggregation.
