The irregular antibodies are other than antibodies from ABO blood group system because of pregnancies and blood transfusions, clinical autoimmune, drug-induced etc. The irregular IgG and/or IgM antibodies emerge and lead to the difficult identification of clinical blood type, difficult matching of blood, hemolytic disease of newborn, hemolytic transfusion reaction, and so on. It is very necessary to screen and identify the irregular antibodies before blood transfusion or antepartum. For some difficult identifying samples, some detections on serological level should be done firstly, combining with flow cytometry analysis, the difficult-matching patients' genotypes and fetal genotypes were detected by molecular biology techniques such as PCR and PCR-SSP in order to further predict fetal hemolytic disease of newborn and to provide the right blood to difficult-matching patients, and free fetal DNA extracted from maternal plasma. So that some measures must early be taken for clinical prevention and treatment to reduce immune hemolytic reactions. In this paper, the emergence of irregular antibodies, species, laboratory testing, pathogenesis, clinical symptoms and the current research are reviewed.
