LOINC code93940-5
nameD Ag [Presence] on Red Blood Cells --during infancy
descriptionDuring 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).
