To assess the effectiveness of a system of preventing incompatible blood transfusions resulting from the misidentification of patient specimens, a prospective analysis of all blood samples submitted to a laboratory was performed.
Incorrectly labeled specimens (rejected samples) were tested for ABO and Rh type, and routine antibody screens were performed. Test results were compared to historic patient data or patient data obtained from subsequently submitted (correctly) labeled specimens. For comparison, all discrepant serologic results from appropriately labeled samples were also recorded.
Specimens that failed to meet the criteria for specimen acceptance were 40 times more likely to have a blood grouping discrepancy.
Strict adherence to the labeling requirements results in a significant decrease in erroneous blood grouping. This would accordingly diminish the likelihood of transfusing out-of-group blood components.
为评估一个预防因患者标本误识别导致的不相容输血系统的有效性，对提交至某实验室的所有血样进行了前瞻性分析。
对标签错误的标本（拒收样本）进行ABO和Rh血型检测，并进行常规抗体筛查。将检测结果与历史患者数据或从随后提交的（正确）标签标本中获得的患者数据进行比较。为作比较，还记录了来自标签正确样本的所有不一致血清学结果。
不符合标本验收标准的标本出现血型不符的可能性高40倍。
严格遵守标签要求可显著减少血型错误。这相应地会降低输注不相合血液成分的可能性。
