全血白细胞计数危急值与临床的关系

Analysis of whole blood white blood cell count critical value and its clinical distribution.

目的探讨全血白细胞计数危急值与临床的关系。方法统计2009年1月至2011年1月期间本院医学检验部检测到的所有危急值,并通过查阅病历回顾性分析全血白细胞计数危急值患者的相关临床资料,分析其特点及分布规律。结果共报告危急值2865个,其中全血白细胞危急值156个,共报告全血白细胞计数192960个测试,报出率为0.08%,占所有报告危急值的5.44%。高危急值病例主要在急性感染患者多见,其次为白血病、急性出血、恶性肿瘤、大手术后、烧伤以及肾功能衰竭患者;低危急值病例主要在白血病患者多见,其次为化疗后的恶性肿瘤患者。结论全血白细胞计数危急值上下限的确定直接影响了全血白细胞计数危急值的报出率,应科学合理地设置危急值范围,分析其特点及疾病的分布规律,以便更好地服务于临床。

Objective To investigate the relationship between the critical value of the whole blood white blood cell count and the clinic. Methods The critical value of the whole blood white blood cell count from January 2009 to January 2011 in our hospital and its distribution were analyzed through medical records and patient clinical data. Results A total of 2 865 critical values were reported, of which 156 were critical value of the whole blood white blood cell count, reporting a total of 192 960 whole blood white blood cell count, with the report rate of 0.08%, accounting for 5.44% of all the reports of critical value. The number of critical value of the whole blood white blood cell count up upper limit was 101 （64.74%） and under lower limit was 55 （35.26%）. Cases of high critical value oeenrred primary in patients with severe acute infection, followed by patients with leukemia, acute hemorrhagic, after major surgery, bum, cancer and renal failure patients. Cases of low critical value occurred primary in patients with leukemia, followed by patients with malignant tumors after chemotherapy. Conclusion The range of critical value of whole blood white blood cell count would determine its report rate. It should be scientific and reasonable to set and analyze the characteristics and the distribution pattern of the disease so as to better serve the clinical practice.
