|Limitation of test||Molecular testing to predict the red blood cell phenotype does not always reflect the phenotypic expression of the blood group antigen. This may occur in cases where the individual has genetic variation that silences or alters the blood group antigen expression that is not included in the target region of the test, and also may occur with RhD zygosity testing. Test results must be interpreted with knowledge of how known polymorphisms affect blood group antigen expression. The performance characteristics have been established by Bloodworks Northwest. The results are not intended as the sole means for clinical diagnosis for donor or patient management decisions.|
