目的:建立可操作性的乳糜血判定标准,在初筛时避免不合格血液的采集,更加合理利用血液,减少乳糜血的报废。方法:选择已申请报废的乳糜血浆330例,用目测法区分为轻、中、重度乳糜,应用4040半自动生化仪通过试剂空白值与样本检测值在吸光度上表现出的差异即乳糜指数CB值来判定乳糜程度;观察CB值超过当日标准空白值≤0.4以下为轻中度乳糜,询问饮食情况可以采集;CB值超过当日标准空白值>0.4以上为重度乳糜,不予采集。结果:通过设定乳糜指数即CB值使乳糜报废率得到有效控制,2014年上下半年乳糜报废率依次为2.26%和1.51%,呈下降趋势。结论:通过加强献血前征询,为初筛检验岗位判定乳糜血提供统一的标准依据,有效避免了人为主观判定乳糜程度的差异,减少乳糜血的报废,合理缓解血源。
OBJECTIVE: To set up a malleable standard for judging cholelithiasis, to avoid the collection of unqualified blood during the initial screening, to make more rational use of the blood and to reduce the scraps of chylomicrons. Methods: Cholesterol plasma was applied in 330 cases, which were divided into mild, moderate and severe chyle by visual inspection method. The 4040 semi-automatic biochemical analyzer was used to measure the absorbency of the chylous index CB value To determine the degree of chyme; observed CB value than the standard value of the day ≤ 0.4 The following is mild to moderate chyme, asked about the diet can be collected; CB value than the standard blank value> 0.4 above for severe chyme, not collected. Results: The chyme rejection rate was effectively controlled by setting the chyle index (CB). In the second half of 2014, the chyme rejection rates were 2.26% and 1.51%, respectively, showing a decreasing trend. Conclusion: By strengthening the pre-donation consultation, it provides a uniform standard basis for screening post-screening chylous blood, effectively avoids the discrepancy of the degree of chyme by subjective judgment, reduces the scrapping of chyle blood, and alleviates the blood supply reasonably.
