Policy: Extended Rh and Kell Phenotyping

Principle:

Based on recent cases of rare phenotypes in the Rh system, we will proactively detect such patients and donors most likely for this.

Policy:

Extended Rh (C, c, E, e) and Kell (K1) typing should be done on all donors and patients meeting the any of the following criteria:

  1. D-negative phenotype
  2. Patients with positive antibody screens
