Abstract

Approximately 2,200 laboratories participated in the 1978 Comprehensive Blood Bank Survey of the College of American Pathologists. Correct responses of the test results on the blood specimens were determined by 13 Referee Laboratories. Participants' results were compared with Reference Laboratory results. Overall performance on ABO and Rh D typing revealed 98.3% concurrence. Errors in ABO grouping and Rh typing were most frequently found to be "clerical" rather than "technical." Antibody studies and crossmatching revealed variable results in the detection, identification, and evaluation of the clinical significance of a weak, naturally occurring antibody (anti-P1) and in the crossmatching of weak immune antibodies (anti-e and anti-D). Over 95% of participants correctly responded on antibody studies and crossmatching results with a serum containing a moderately strong anti-Fya. Ungraded specimens provided during the year yielded "state of the art" information on a variety of problems.

摘要

约2200个实验室参与了1978年美国病理学家学会的综合血库调查。13个裁判实验室确定了血液标本检测结果的正确答案。将参与者的结果与参考实验室的结果进行比较。ABO和Rh D血型分型的总体表现显示一致性为98.3%。ABO血型分组和Rh血型分型中的错误最常被发现是“文书性的”而非“技术性的”。抗体研究和交叉配血在检测、鉴定和评估一种微弱的天然抗体（抗P1）的临床意义以及在微弱免疫抗体（抗e和抗D）的交叉配血方面显示出不同的结果。超过95%的参与者对含有中等强度抗Fya血清的抗体研究和交叉配血结果做出了正确回答。当年提供的未分级标本产生了关于各种问题的“最新技术”信息。
