Clinical Information

Cord blood samples are tested to determine the ABO/Rh type of the infant and to detect the presence of ABO, Rh, or other antibodies potentially involved in hemolytic disease of the newborn (HDN).

 

Cord blood specimens may be contaminated with Wharton's jelly and other cord contaminants. The red cells from cord specimens must be washed thoroughly before they are tested. Newborns do not have their own ABO antibodies, therefore ABO reverse type is not performed.

 

Providers will order a Cord Blood Workup on the infant in the hospital information system, including the entry of the mother’s MRN as part of the order which can be helpful to determine if HDN testing should be performed. It is also used to compare identifying information on the specimen label.
