Objective To choose a more reliable method to determine the hemoglobin concentration of blood donors in order to further improve the accuracy. Methods On the basis of gold standard method for the detection of hemoglobin (HiCN method), we used blood cell analyzer as the control group. Comparison test was carried out between visual reagent on hemoglobin (copper sulfate proportion) and dry hemoglobin test paper. Results Regression analysis of 151 cases of data samples with confidence degree P =95% was carried out. Comparison of Uritest detection(y) and Sysmex reference(x), y=0.892 2x+15.979, R2=0.7461; comparison of Hemocue detection(y) and Sysmex reference(x), y=0.949 4x+15.018, R2=0.838 1. Conclusion Determination of hemoglobin with dry hemoglobin test paper is a method with similar sensitivity and stability with that of the method using blood cell analyzer. The precision, accuracy and linear degree fully meet the needs of testing. It has practical significance in especially blood screening test in blood banks.

<正>目的为了保证对血小板运输过程的有效控制,通过对2种不同控温类型(车载式控温和固定冰点材料控温)的运输箱运输血小板的情况进行比较,建立对2种不同控温类型的运输箱运输血小板的方法。方法在不同的外环境温度下(分别为2～10℃、15～30℃和43℃),比较0～5h时间段,这2种不同控温类型血小板运输箱内温度情况,计算不同情况下运输箱维持预期温度的时间。同时检测其箱内血小板的数量和血小板pH值变化情况。结果当外环境为2～10℃,在4.5h以内,车载式控温血小板运输箱其箱内的温度始终在20～24℃温度范围,其血小板计数和pH值均无统计学意义;
