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.
