Analysis of antibody potency of IgG blood group in O-type blood pregnant women by three methods / 中国输血杂志

ABSTRACT

Objective To investigate the effect of microcolumn gel reagent card,micro-column glass bead reagent card and classical test tube on the antibody titer of O-type pregnant women with ABO blood group.Determination of antibody potency of pregnant women with rabbit by reagent card.Methods Using microcolumn gel reagent card,micro-column glass beads reagent card,and classical test tube parallel detection to detect the IgG blood group antibody titer of O blood type pregnant women.Results There was no significant difference in the positive detection rate between the microcolumn gel reagent card and the microcolumn glass beads reagent card at 1:128 and the test tube method at 1:64 (P＞0.05).Conclusion The clinical reference value of microcolumn gel reagent card and microcolumn glass beads reagent kit for detecting antibody titer of IgG blood group in O-type pregnant women should be set to ≥ 1:128.
