Test Information: Purpose of the test is to monitor patients after transplant for the presence and level of antibodies to the donor’s HLA antigens. The test is semi-quantitative. Sample Requirements: Clotted blood or Serum: Requested Volume: One 7-10 ml tube of clotted blood (red top) Minimum Volume or Pediatric volume: 2ml clotted blood

2022年3月12日 · Donor specific Antibodies (DSA) are one of the established biomarkers for predicting antibody mediated rejection (ABMR). This blog is a short synopsis on DSA and their complex characteristics in kidney transplantation. DSA may be preformed (before transplantation) or de-novo (developing after transplantation).

Understanding the complexities and limitations of DSA detection techniques is key for making an accurate risk assessment while improving access to transplantation. The goal of this overview is to provide a practical guide for using solid phase assays and crossmatch (XM) testing.

Donor-specific antibodies (DSA) are a concept in transplantation medicine and describe the presence of antibodies specific to the Donor's HLA-Molecules. These antibodies can cause antibody-mediated rejection and are therefore considered a contraindication against transplantation in most cases. [1]

Donor-specific anti-HLA antibodies (DSA) are an important cause of engraftment failure and may negatively impact survival outcomes of patients receiving allogeneic hematopoietic stem cell transplantation (HSCT) using an HLA-mismatched allograft.

HLA Antibody Specificity is used when the identification of HLA antibodies is needed after a screen detects the presence of HLA antibodies. The high specificity and sensitivity of this solid phase single antigen assay allows us to detect and identify low-levels of precise antibodies.

The high specificity and sensitivity of the current solid phase single antigen assay allow us the detection of low-level of the precise DSA. The detection of DSA in pre-transplant evaluation is an excellent tool for risk assessment and crossmatch prediction (Virtual Crossmatch and CPRA).

The antibodies directed to the possible donor and already transplanted organ are known as Donor Specific Antibodies (DSA). These DSA are associated with an increased risk of graft loss and/or rejection.

Based on our knowledge that donor specific anti-HLA antibodies (DSA) are a major cause of allograft loss, determining how to monitor patients for DSA and how to treat them is important. Current published studies indicate that patients with preformed DSA differ from those without.

2012年5月20日 · diagnostic testing methodology in most transplant centers within the US. Large cohort studies of over 5000 transplant recipients indicate that at any given time, approximately 25% of trans -
