Abstract:
【Objective】 To observe the distribution of the unexpected antibodies in order to study the safety and strategies in 1 779 cases of clinical blood transfusion. 【Methods】 A total of 1 779 patients with unexpected antibodies were enrolled from transfusion candidates in various hospitals in Xi′an during a 10-year period(from 2012 to 2022.5). 【Results】 The unexpected antibodies were detected in 926(52.05%) of 1779 samples. The detected antibodies were mainly from 8 blood group systems and their distributions were as follows: Rh antibodies in 69.76%(646/926), Kidd in 2.59%(24/926), Lewis in 4.21%(39/926), MNS in 12.53%(116/926), P in 0.43%(4/926), Diego in 0.65%(6/926), Duffy in 0.54%(5/926), I in 0.97%(9/926), Rh+ MNS in 1.30%(12/926), Rh+ Lewis in 0.65%(6/926), Rh+ Kidd in 3.24%(30/926), Rh+ Diego in 1.51%(14/926), Rh+ Duffy in 0.86%(8/926), MNS+ Diego in 0.11%(1/926), Rh+ MNS+ Kidd in 0.22%(2/926), Rh+ Lewis+ Kidd in 0.22%(2/926), Rh+ Kidd+ P in 0.11%(1/926), Rh+ Kidd+ Diego in 0.11%(1/926). 【Conclusion】 According to the distribution of unexpected antibodies in Xi′an, antibodies from Rh system, were the most common ones.First, the production of unexpected antibodies can be effectively reduced by establishing Rh compatible blood transfusion. Secondly, antibody screen cells containing low-frequency antigens, such as Mur, Dia and Wra, should be reasonably selected to prevent missing detection of anti-low frequency antigen antibodies in Xi′an. Furthermore, the genotyping technology of rare blood group should be promoted and a rare blood group red blood cell bank be established to optimize the blood inventory and ensure the safety of blood transfusion.
