  • Patent number: 7135302
    Abstract: The present invention relates to a method for predicting whether or not transplant recipients are likely to reject tissue allografts. It is based, at least in part, on the discovery that, based on analysis of three immunologic factors, cardiac transplant recipients could be classified into risk categories for progression to high-grade rejection. The present invention, by enabling a determination of the risk for high-risk rejection in a transplant patient, reduces unnecessary diagnostic and therapeutic procedures in low risk patients and clinical intervention in patients who would most benefit.
