Relationship between anti-A(B)IgG titers of pregnant women and neonatal jaundice

Objective:To investigate the relationship between anti-A(B)IgG titers of pregnant women and neonatal jaundice.Methods:One hundred fifty-four pregnant women of blood type O,whose husbands' blood type was not O,were determined of their Anti-A(B) IgG titers.Meanwhile,the blood type and serum total bilirubin of their neonatorum were detected.Results:When the Serum anti-A(B)IgG titers were≤32,64,128,and ≥256 in pregnant women,the incidences of neonatal jaundice were 7.69%,13.63%,27.77% and 71.42%,respectively.Conclusions:The incidence of neonatal jaundice is positively correlated to anti-A(B)IgG titers in pregnant women.
