LOINC description : During the first 4-6 months of life reverse grouping on infants may reflect maternal
antibodies and it may take several months for newborns to develop their own antibodies
against the A and B antigens not present on their own cells. Because of this, blood
typing of infants often involves only forward grouping. In some jurisdictions, legislation
dictates confirmation of blood grouping after a certain age (6 months in France).;
