目的研究血小板计数异常的发生原因,以及质量控制措施。方法将我院血小板计数异常患者80例作为研究对象,分析血小板计数异常的影响因素,制定并实施质控措施。结果采血因素(32.5%)、抗凝剂依赖(25.0%)、PLT体积增大(18.8%)、小红细胞影响(15.0%)、乳糜血因素(8.7%)是导致血小板计数异常的原因。纠正值和测定值相比,差异有统计学意义(P<0.05)。结论影响血小板计数异常的因素较多,采用质控措施加强检测质量,能够提高测定准确性。
Objective To study the causes of abnormal platelet count and quality control measures. Methods Eighty patients with abnormal platelet count in our hospital were studied. The influencing factors of platelet count abnormalities were analyzed and quality control measures were formulated and implemented. Results Blood sampling (32.5%), anticoagulant dependence (25.0%), PLT volume increase (18.8%), small red blood cell effect (15.0%) and chyle blood factor (8.7%) were the causes of abnormal platelet count. Correction value and the measured value, the difference was statistically significant (P <0.05). Conclusion There are many factors that affect the abnormal platelet count. Using quality control measures to improve the quality of detection can improve the accuracy of the assay.
