Genotyping and Phenotyping

75% of our respondents provide phenotype or genotype matched units and so they use this tool both for understanding what patient what aloe antibodies patients may make as well as to select units for transfusion. Genotyping plays a role in patients who are heavily transfused where you can't get a phenotype predominantly. It's not something that we use routinely at UCLA we don't have ready access to genotyping and so the turnaround time is is really slow. We'll talk about antigen matching briefly with Ulyssa because obviously there's there's more to come with that.
