ABO Rh Typing

From MedLabWiki
  • Babies: perform forward testing ONLY
  • Babies: if baby appears Rh Negative and the mother is Rh Negative, perform weak D testing
  • AB Rh Positive patients require Rh Control to be performed
    • RHC should be a reaction of 0. This checks that the agglutination seen is not a result of autoagglutination in the patient.
  • Rh Control is also used for discrepancies (Rh testing results don't match, e.g. Anti-D1 is 2+ and Anti-D2 is 0)
  • Rh Control is also used for IAT Testing (e.g., Weak D testing)
