Abstract: Fetomaternal hemorrhage (FMH) is a series of reactions in which fetal red blood cells enter the maternal circulation before or during delivery, and the mother produces antibodies against fetal red blood cells, which in combination with red blood cell surface antigens cause fetal red blood cells to undergo varying degrees of hemolysis. Accurate quantification of fetalmaternal hemorrhage is crucial for the prevention of neonatal birth defects including neonatal hemolytic disease. Based on the latest relevant literature at home and abroad, this article analyzes the new and traditional detection methods for FMH, elucidates the advantages and shortcomings of various detection methods, and briefly outlines the correlation between FMH and various perinatal fetal clinical disorders, in order to provide a basis for standardization of testing techniques for fetalmaternal hemorrhage and further prevention and treatment of related diseases.

Key words: Foetomaternal haemorrhage, Detection methods, Clinical relevance
