[34] The patient's skin is typically cleaned with an alcohol-based product prior to drawing blood to prevent contamination. [34] Blood cultures may be repeated at intervals to ...
Some mothers may be sensitized by fetal-maternal transfusion of ABO incompatible red blood and produce immune IgG antibodies against the antigen they do not have and their baby does. For example, when a mother of genotype OO (blood group O) carries a fetus of genotype AO (blood group A) she may produce IgG anti-A antibodies. The father will ...
