Abstract:
OBJECTIVE:To retrospectively analyze the identification results of irregular antibodies, to clarify the distribution features and to explore the relation of alloantibodies and autoantibodies with the immunized history of patients and disease kinds.
METHODS:49 820 patients who applied for red blood transfusion during Sep 1st 2017 to Sep 1st 2018 were selected. All the specimens were screened for the antibody by microcolumn gel antiglobulin technique, which then were identified for irregular antibody.
RESULTS:Antibodies were found in 861 (1.73%) of all 49 820 transfused samples. The alloimmunization history of the patients with antibodies was significantly different between male and female (χ=18.54，P＜0.01). The alloantibody was the most common, accounting for 59.50% in all of the antibodies. Warm autoantibody, anti-E, anti-M, anti-cE and anti-Ce accounted for 68.5% of the antibodies. The blood group of Rh, MNS and Lewis were responsible for 92.40% of alloantibody, especially anti-E accounted for the largest percentage(38.60%) of alloantibody. Patients with alloantiboies experienced much more the alloimmunization and transfusion history (χ=20.13，P＜0.01；χ=5.40，P＜0.05) . The distribution of auto and alloantibody was very significantly different among the ddifferent isease (χ=51.8，P＜0.01), Hematopathy, solid tumor and osteoarthropathy were often associated with alloantibody, otherwise, autoantibodies often occurred in hematopathy and autoimmune disease.
CONCLUSION:The most important factor that results in antibody-screening positive is alloantibody, in which anti-E antibody from Rh blood group system in most common.
