Abstract
Alloantibodies are the major cause of hemolytic transfusion reaction and newborn hemolytic disease. It is highly recommended to screen alloantibodies before transfusion and pregnancy. This report applied the microcolum gel method to screen for available alloantibodies, enrolling 20,098 patients from January 2016 to December 2017 in the Xinjiang General Hospital. Seventy-two patients were found alloantibody-positive, at an overall positive rate of 0.35%. The distribution of alloantibody varied according to age, gender or treatment. The patients aged 70 plus and the patients admitted in the Department of Hematology and Department of Gynecology & Obstetrics had a higher incidence rate of alloantibodies. By using 10 screening cell panel systems, 9 types of alloantibodies including anti-D, anti-E, anti-e, anti-C, anti-c, anti-M, anti-s, anti-Fy<sup>b</sup> and anti-Ce were identified. This study suggests that the transfusion of red blood cells(RBCs) and pregnancy are the main causes of alloantibodies.
