【摘 要】 目的:觀察微柱凝胶卡式法经不同标本及处理方式对交叉配血试验结果的影响。方法:本次试验研究材料是40例凝块血液标本及80例需要接收输血患者的血液标本,对比是否血样抗凝及不同程度的红细胞悬液浓度对交叉配血试验结果的影响。结果:对比EDTA-K2抗凝组,普通促凝组的阳性率显著增高,资料对比,存在显著差异性(P<0.05);对比EDTA-K2抗凝组,不完全抗凝组的阳性率显著增高,资料对比,存在显著差异性(P<0.05);比较低浓度红细胞悬液,大于1%的红细胞悬液浓度假阳性比例较高,资料对比,差异性不显著(P>0.05);比较低浓度红细胞悬液,2%的红细胞悬液浓度假阳性比例更高,资料对比,存在显著差异性(P<0.05);比较低浓度红细胞悬液,大于2%的红细胞悬液浓度出现完全假阳性,资料对比,存在显著差异性(P<0.05)。结论:若没有有效处理血样标本或存在过高的红细胞浓度,微柱凝胶卡式法交叉配血试验很容易出现假阳性。

【Abstract】Objective To observe the effect of microcolumn gel cross matching test on blood samples without specimen and treatment. Methods 40 blood samples of clots and 80 blood samples of patients who need to receive blood transfusion were used in this study. Results compared with EDTA-K2 anticoagulant group, the positive rate of common anticoagulant group was significantly higher, there was significant difference (P < 0.05); compared with EDTA-K2 anticoagulant group, the positive rate of incomplete anticoagulant group was significantly higher, there was significant difference (P < 0.05); compared with low concentration red blood cell suspension, the false-positive rate of more than 1% red blood cell suspension was higher, and the data was correct. There was no significant difference (P > 0.05); compared with the low concentration of red blood cell suspension, the false-positive ratio of 2% of red blood cell suspension was higher, there was significant difference in data comparison (P < 0.05); compared with the low concentration of red blood cell suspension, there was complete false-positive in the concentration of more than 2% of red blood cell suspension, there was significant difference in data comparison (P < 0.05). Conclusion if there is no effective treatment of blood samples or excessive red blood cell concentration, microcolumn gel card cross matching test is prone to false-positive.
在医学水平快速发展中,临床中开始将输血治疗作为常用的急救措施,需由供血者与受血者在输血前进行交叉配血检查,防止有溶血反应出现,对受血者生命安全造成影响,交叉配血检查法是临床常用方式,具有较高的准确性,但很难操作,微柱凝胶法是一种新型交叉配血检查法,具有较高的灵敏度。本课题主要对微柱凝胶卡式法经不同标本及处理方式对交叉配血试验结果的影响进行分析,报道如下:
1 资料与方法
1.1资料
本次试验研究材料是40例凝块血液标本及80例需要接收输血患者的血液标本,患者血液标本中,每例采集两管2.5毫升血液,将其分别收集到普通促凝管组与EDTA-K2抗凝管组,各80例,将EDTA-K2抗凝管中出现的40例凝块血样作为不完全抗凝组。
1.2 方法
微柱凝胶法基础操作方法:血样离心分离供血者与受血者血……
