Identification and Analysis of Irregular Antibodies in Hospitalized Patients Prepared to Accept Blood Transfusion
Objective:To analyze the type and distribution characteristics of irregular antibodies in 71847 hospitalized patients who prepared to accept blood transfusion,and to explore their role in safe blood transfusion. Methods:71847 patients who applied for red blood transfusion from January 2020 to October 2023 were selected.All specimens were screened and identified for the irregular antibody by microcolumn gel antiglobulin technique.Results:Among the 71847 patients preparing for accept blood transfusion,301 cases tested positive for irregular antibodies (0.42%).Of these 301 antibody-positive patients,252 (83.72%)exhibited alloantibodies.The Rh blood group system was the most common,accounting for 179 cases (59.47%).Antibodies in Rh blood group system included anti-E (135,44.85%),anti-E+c (24,7.97%),anti-C+e (10,3.32%),anti-c (6,1.99%),anti-D (3,1.00%),and anti-D+C (1,0.33%).By analyzing 301 cases with irregular antibodies,it found the positive rate of>60 years old group was higher than that in≤60 years old (0.61%vs 0.33%),female group was higher than that in male group (0.50% vs 0.31%),internal medicine and gynaecology and obstetrics groups were both higher than that in surgery group (1.25% vs 0.20%;0.32% vs 0.20%),group with pregnancy/transfusion history was higher than that in non-pregnancy/transfusion history (0.64% vs 0.13%),the differences were statistically significant (P<0.05). Conclusion:In the routine monitoring of the blood group,it is necessary to detect RhE,so as to reduce the positive rate of irregular antibodies greatly and further ensure the safety of blood transfusion.
