The First Affiliated Hospital of Hunan Normal University, Hunan Provicial People's Hospital, Changsha 410006, China; 2. Traffic Hospital of Hunan Province, Changsha 410000, China Liu Qiong1, Liu Mi2[Abstract] Obejective To understand the morbidity of ABO hemolytic disease of the newborn in Changsha, discuss the clinical significance of three serologic tests to diagnose the ABO hemolytic disease of the newborn and provide evidences for the early prevention, early diagnosis and clinical treatment of the disease. Methods Collecting the total of 583 cases of maternofe-tal ABO incompatibility from January 2016 to July in Xiangya Hospital of Central South University. The ABO blood group and serologic tests were determined. Results There are 145 cases of HDN in the total of 583 blood samples with the incidence 24.87%. The number of male children was 80 (25.64% and female children was 65(23.98%. There was no significance differ-ence in their incidences. In 145 cses of ABO-HDN with positive result in 90 cases with O-A incompatible pregnancies (54.88%, 55 cases with O-B incompatible pregnancies (41.35%, as a result, there were differences between these two blood group and the incidence of type A was higher than type B. In 145 cases of ABO-HDN, the direct antiglobulin test (DAT with positive result was 38(26.21%, free antibody test was 76 (52.41% and the RBC antibody release test was 144(99.31%. There were differences among the three serological tests. Conclusion The morbidity of ABO-HDN in changsha is about 24.87%. No dif-ference was found between the male children and female children. The three serological hemolytic tests are the most important methods for diagnosis of ABO-HDN, in which the most sensitive is RBC antibody release test, followed by free antibody test and DAT. The three serologic tests are helpful in the early prevention, early diagnosis and clinical treatment of the disease.[Key words] hemolytic disease of newborn; ABO; RBC antibody release test; DAT; free antibody test ABO血型新生儿溶血病（hemolytic disease of the new-born，HDN）指的是母婴
