目的:分析2007年6月-2010年5月街头初筛丙氨酸氨基转移酶(ALT)不合格率与性别以及季节的变化关系,寻找其中原因及应对措施,对不同性别人群采取不同的ALT判断标准提供参考,从而减少血源浪费。方法:收集洛阳地区参与街头无偿献血初筛者(包括初筛合格以及单纯ALT不合格者)的资料,运用统计学方法分析街头初筛ALT不合格率与性别及季节的关系。结果:男性ALT不合格率明显高于女性,不论男女每年2、8、9月份都是ALT不合格的高发时段。结论:规范操作,加强生化仪的日常维护,减少人为因素造成的ALT不合格率,同时加强对献血者尤其是男性献血前饮食、休息等注意事项的宣传,将减少因ALT不合格而造成的血源浪费。
OBJECTIVE: To analyze the relationship between the incidence of debriding ALT and the sex and seasonal changes in the street from June 2007 to May 2010, and to find out the reasons and the countermeasures. The different ALT Judgment standards provide a reference, thereby reducing blood waste. Methods: The data of unprotected blood donors in the streets of Luoyang were collected, including those who passed primary screening and those who did not pass the ALT. Statistical analysis was conducted to analyze the relationship between ALT failure rate and gender and season in street screening. Results: Male patients with ALT failure rate was significantly higher than women, both men and women each year 2, 8, 9 months are ALT unqualified high incidence period. CONCLUSIONS: Standardizing the operation, strengthening routine maintenance of biochemical analyzer, reducing the ALT failure rate caused by human factors, and promoting publicity on precautions of blood donors, especially men before giving blood donation, will reduce the risk of ALT failure Blood waste.
