An establishment of the procedures to eliminate incorrect blood due to non-matched or mislabeled tubes

Abstract

This study aims to establish a set of procedures to eliminate incorrect blood due to non-matched tubes or mislabeled tubes. The errors such as these are suspected to have occurred when upon first and second-detection. Under the identical laboratory conditions, the results of re-detection of blood bag samples and rare type antigen samples, as well as re-collected samples from donor, and plasma diluted are not consistent with the original results. Here, 20 antigen erythrocytes were detected for blood bag samples and original samples, in which no incorrect blood was mistakenly administered or mislabeled. Samples taken under identical laboratory conditions were not found to have incorrect blood administered to a non-matched tube. The results showed nonlinear changes by HBsAg ELSIA after plasma dilution. The study suggests that the second-detection taken shortly after first detection is the most appropriate method to detect errors at the earliest time point. Blood bag samples are identical to those of the original antigen identification group, which means that the probability of the samples coming from the same donor is extremely highly. At same time, space and plasma diluted, re-detection can effectively exclude incorrect blood being added to a non-matched tube.
