An automated readout device recording light transmission in the eight channels of the BG-8, blood-grouping machine after removal of agglutinates is described. Using a continuous recording of positive or negative signals in the eight channels independently, 7.5% of 10,000 blood group determinations had to be retested because of clots in the samples, lacking reactions or excess reactions on the recorder. No incorrect recordings of blood groups were obtained, however. Using anti-D serum together with anti-CDE serum, the rhesus D factor was correctly detected in 99.92% of 3,891 samples, and the Du factor was detected in all 5 samples known to carry this antigen. Using a discontinuous recording of integrated and synchronised signals, adapted to fully automated data processing, another 5% of the samples had to be retested because of inadequate phasing of the reactions in the eight channels of the BQ-8. The results described are influenced by the poor quality of the blood samples used for the study.
本文描述了一种自动读数装置，该装置用于记录在去除凝集物后BG - 8血型分析仪八个通道中的光透射情况。通过独立连续记录八个通道中的正信号或负信号，在10,000次血型测定中，有7.5%因样本中有凝块、记录器上反应缺失或反应过度而需要重新检测。然而，未获得血型的错误记录。使用抗-D血清和抗-CDE血清，在3891份样本中，99.92%的样本正确检测出了恒河猴D因子，并且在所有已知携带该抗原的5份样本中检测出了Du因子。使用适用于全自动数据处理的集成和同步信号的不连续记录方式时，由于BQ - 8八个通道中反应的相位调整不当，另外5%的样本需要重新检测。所描述的结果受到用于该研究的血液样本质量较差的影响。
