For infants less than four months old during any single hospital admission, testing for red cell antibodies, compatibility testing and ABO Rh typing may be omitted if an initial ABO/Rh typing and antibody screen has been performed and Group O Red Cell components are issued. If the antibody screen is positive, an infant is eligible for the protocol as long as the donor unit can be tested for the corresponding antigen. Please note: requires the ordering facility to submit written procedures to Compatibility Testing Laboratory for review.

Initial testing includes ABO/Rh and antibody screen on the recipient. A direct antiglobulin test is performed, if ordered, on the recipient. ABO compatibility of the donor unit is determined and ABO/Rh of the donor unit is confirmed.

To order, use Infant Protocol Request for Blood.
