Q82
Single choice
If all newborns were tested, many positive DATs due to ABO incompatibility would be detected that are of no clinical significance.
Although many laboratories test infants born to group O Rh positive females due to the higher risk of ABO HDFN when the mother is group O, testing such infants is optional provided there is appropriate monitoring and follow-up for hyperbilirubinemia.

Not performing direct antiglobulin tests (DATs) on newborns born to group O Rh positive mothers is acceptable good practice, providing there is appropriate surveillance and follow-up to detect hyperbilirubinemia.
