ABSTRACT

Objective To study the relationship between antibody-rdeased test and the morbidity of hyperbilirubinemia in newborns.Methods According to the laboratory rules,serological tests were practised with neonatal umbilical blood of 1 013 A or B blood-type neonates delivered by O-type blood mothers.The morbidity of hyperbilirubinemia were grouping studied in 7 days after birth tO the neonates according to test results.Results(1)The morbidity of hyperbilirubinemia neonates with positive antibody release test results was much higher than that of control group(P＜0.01).(2)Of the antibody release test positive results,there were significant differences among the three groups in which the degree of red cell agglutination were different (P＜0.01).(3)Of the antibody-released test positive results,there was no significant difference in the morbidity of hyperbihrubinemia between the neonates sensitized by the anti-A+B IgG and those not sensitized by the anti-A+B IgG(P＞0.05).There had significant difference in the morbidity of hyperbilirubinemia between the neonates with free antibody and those without free antibody(P＜0.01).Conclusion The different results of antibody release test play some role in the clinical judgement whether hyperbilirubinemia of newborns will occur.
