Question
What does a HDN maternal IgG antibody titer of 1:512 mean? What precautions should be taken? Do you need medication treatment?
Answer
A HDN maternal IgG antibody titer of 1:512 indicates that the serum needs to be diluted to this ratio before the antibody is undetectable, suggesting a high concentration of the antibody. It may be related to neonatal hemolysis, and it is recommended to observe and take treatment measures if necessary.
