[Abstract] Objective To put forward measures to reduce the blood type inconformity rate and improve the blood quality and safety by analyzing reasons for blood type inconformity among unpaid blood donors. Methods The blood type test data of 193，289 unpaid blood donors in Zhongshan Center Blood Bank from January 2016 to December 2019 were retrospectively analyzed. The blood types of the first blood donors were screened by the cardboard method， and the blood types recorded by the blood information management system for the second blood donors were used as the primary blood types. The blood was collected and reexamined by microplate enzyme plate analyzer to classify and count the numbers of ABO blood type inconformity cases were classified and counted， calculate the inconformity rate， and analyze the reasons for the blood type inconformity. Results From January 2016 to December 2019， a total of 193，289 people were tested for the blood type， including 52，188 cases of type A， 48，322 cases of type B， 79 248 cases of type O and 13，531 cases of type AB. A total of 139 cases of blood type inconformity were found， including 119 cases （85.61%） of blood type inconformity in the primary screening and 23 cases（16.55%） of blood type inconformity between the positive and negative stereotypes. In 119 cases of blood type inconformity， B and A antigen missed detection accounted for 42.86% and 9.24%， respectively. The blood type inconformity in the primary screening was the main cause of blood type inconformity. A total of 8 cases of positive irregular antibody were found， including 2 cases of subtype A， 1 case of subtype B， 2 cases of condensation agglutinin， and 10 cases of other reasons. Conclusion The error of blood type primary screening is the main cause of blood type inconformity. In case of blood type inconformity， the reasons should be analyzed according to specific problems and corresponding treatment measures should be taken to ensure the accuracy of blood type detection and finally ensure the safety of blood for clinical use.
