Red Cell Antigen Genotyping

Ordering information:

This test is available for two purposes :

(1) the prediction of blood group phenotypes in recently transfused patients or patients with autoimmune conditions where the patient’s own immunoglobulins interfere with conventional grouping reagents, or

(2) the prediction of the RhD blood group status, primarily in females who are pregnant, or who are of child bearing age, to assist with appropriate management based on the risk of anti-RhD allo-immunisation.

Please consult the Pathology Department before ordering this test.
