Transfusion registry network providing real-time interaction between users and providers of genetically characterized blood products
View Patent ↗Disclosed is a registry system, including member institutions, in which transfusion donors and recipients are registered following genotyping, which would typically take place in a member institution, or a member institution would have access to the genotyping information, if performed outside. The registry database can be accessed and searched by members seeking samples of particular type(s). Systems are disclosed for maintaining economic viability of genotyping in connection with transfusions, by maximizing the number of units placed with the minimal number of candidate donors typed. Genotyping of potential donors, and product supply, is matched to forecasted demand. Genotyping can also be limited to the more clinically relevant markers. The registry system can also be integrated with one format of assay which generates an image for analysis, whereby the imaged results can be analyzed and redacted by experts in a central location, and then transmitted back to the patient or their representative.
1. A method for reducing the incidence of allo-immunization in recipients transfused by samples obtained from member institutions below that otherwise experienced, where member institutions form a registry which retains a database of genotyped donors, and where certain member institutions perform transfusions to recipients, comprising:
requiring that certain member institutions genotype donors for certain molecular markers associated with clinically significant events;
maintaining the genetic marker information associated with the genotyped donors and the samples which they donate;
requiring that certain member institutions genotype or phenotype recipients for said markers; and
transfusing blood, serum or tissues to recipients only if the donor genotype precludes the expression of said molecular markers by said donors.
2. The nethod of claim 1 wherein the molecular markers relate to blood group antigen groups including RhCE, Kidd, Kell, Duffy, Dombrock, MNS, and combinations of markers from RhCE, Kidd, Kell, Duffy, Dombrock and MNS.
