目的 探讨血葡萄糖危急值与临床的关系。方法 统计2012年1月至2014年1月湖北省谷城县人民医院检验科检测到的危急值，分析血清葡萄糖危急值特点及其分布规律。结果 共报道危急值3349例，血清葡萄糖216例占6.45 %，其中低血糖危急值71例占33%，高血糖危急值145 例67%；危急值病例主要在消化系统疾病以及糖尿病患者中多见。结论 本院血糖危急值的限值范围略窄，应根据情况科学合理地设置危急值范围。

Objective To explore the relationship between serum glucose critical value and the clinical practice. Methods The critical value detected in our clinical laboratory from January 2012 to January 2014 were recorded, and the serum glucose critical value characteristics and distribution rule were analyzed. Results 3349 cases of critical value were reported. The serum glucose accounted for 216 cases (6.45%). Among them, the critical value of hypoglycaemia was 71 cases (33%), and high blood sugar critical value was 145 cases (67%). The critical value cases were mainly found in the digestive system diseases and diabetes. Conclusion The limit scope of our serum sugar critical value is too narrow, and the critical value range could be set up scientifically based on the actual situation.
