Molecular Laboratory

A Molecular Laboratory performs genotyping for the following red cell antigens:

  • RhCE
  • Kidd
  • MNS
  • Dombrock
  • Catwright
  • Kell
  • Duffy
  • Diego
  • Colton

Molecular testing is also performed for platelet antigens, HPA-1a/b.

The benefits of blood group genotyping:

  • Provides an accurate genotype and predicted phenotype for patients when serology is limited due to recent transfusion, multiple transfusions, or patient red cells coated with immunoglobins.
  • Provides alternate method for blood typing when antisera is not available.
  • Provides extensive donor screening for relevant red blood cell antigens in a timely manner.
