提高筛选献血员ALT标准对献血员初复检合格率的影响

Study on the Impact of Raising of ALT Thresholds for Blood Donors on the Pass Rates of Initial-examination and Re-examination

目的 观察改变筛选献血员ALT临界值对初复检合格率的影响.方法 对初复检与快速筛选方法进行直线相关分析并得出回归方程,然后拟定提高快速筛选临界值,观察初复检合格率.结果 初检值=-1.1886 ＋06137×快速值;复检值=-1.4018 ＋0.4821×快速值,快速筛选临界值提高5U和10U,初复检合格率均为100％.献血员合格率也显著提高.结论 将献血员快速筛选临界值初复检的值增加5～10U,在不影响血液的质量前提下,可显著增加献血员合格率.

Objective To explore the impact of increase of ALT thresholds for blood donors on the pass rates of first-examination and second-examination. Methods The correlations between analysis results of ALT of initial- examination and re-examination with rapid screening methods were determined with linear correlation analysis. The re-examination pass rates were observed by improve rapid screening thresholds based on the above derived equations. Results The initial examination value of ALT was calculated as 1. 1886 ＋ 06137 × rapid screening value,and the re-examination value was calculated as 1. 4018 ＋ 0. 4821 × rapid screening value. After increasing 5U or 10U of thresholds of rapid screening value, the initial and re-examination pass rate was all 100%. The pass rates of blood donors were significantly increased. Conclusion The Threshold value of ALT in rapid screening of blood donors could be increased by 5-10 U without affecting the quality of the blood.
