Background:
The Virtual crossmatch (VXM) assesses immunologic compatibility between recipient and potential donor through an in silico analysis of a recipient’s HLA antibody profile cross referenced against a donor’s HLA type. The goal of VXM is pre-transplant risk stratification—though there is no consensus on whether such risk assessment involves predicting the PXM result or the posttransplant outcome. Although the concept of VXM is not new, the wide application of single antigen bead assays for accurate and sensitive detection of recipient HLA antibodies and molecular methods for typing donor HLA at a higher resolution makes the routine use of VXM a reality. Implementation of VXMs allowed for expedited allocation of donor organs leading to reduced cold ischemia time without an increase in hyperacute rejection episodes. New regulations from CMS now consider VXM as a suitable alternative to cell-based crossmatches. In this webinar, we will be discussing new CMS guidelines related to VXM, and its impact on the transplant programs, HLA laboratories, and offer accepting providers standpoint.
