新生儿败血症是新生儿期细菌、真菌等侵入血液生长繁殖且产生毒素引起全身性的感染[1];在发达国家发病率为0.1%~0.4%,病死率为5%左右;国内病死率为12.0%~20.5%[2]。故早期诊断、正确治疗对降低新生儿病死率有重要意义[3]。本文就新生儿败血症的实验室检查进行探讨与研究,为临床研究提供信息。1血常规1.1白细胞(WBC)全血细胞中提示感染的异常指 Neonatal sepsis is a neonatal period of bacteria, fungi and other invasive blood growth and produce toxins and cause systemic infection [1]; in developed countries incidence of 0.1% to 0.4%, the case fatality rate of about 5%; the domestic mortality rate was 12.0% ~ 20.5% [2]. Therefore, early diagnosis and correct treatment of neonatal mortality reduction is of great significance [3]. In this paper, neonatal sepsis laboratory examination and research to provide information for clinical research. 1 blood 1.1 1.1 white blood cells (WBC) abnormal blood cells prompted infection
