DSA (Donor Specific IgG Antibodies to Class I & II)
The DSA test detects antibodies in the recipient’s blood that are directed against the donor’s organ after transplantation. It is critical for evaluating transplant rejection and managing post-transplant care. The test helps identify patients at risk for graft rejection.
Overview of DSA (Donor Specific IgG Antibodies to Class I & II) in Alappuzha
What is DSA, Donor Specific IgG Antibodies to Class I & II test?
What is DSA, Donor Specific IgG Antibodies to Class I & II test is a blood test that detects IgG antibodies in a transplant recipient directed specifically against the donor’s HLA Class I (A, B, C) and Class II (DR, DQ, DP) antigens, which are a major cause of antibody‑mediated graft injury and rejection.
Why consider DSA, Donor Specific IgG Antibodies to Class I & II test in Alappuzha?
Presence of DSA is strongly associated with antibody‑mediated rejection (AMR), graft dysfunction, and inferior graft survival across solid organ transplants, making it critical for risk assessment and monitoring.
Complement‑binding or certain IgG subclasses (notably IgG1/IgG3) indicate higher pathogenic potential, helping refine risk stratification and management decisions.
Who should get this DSA, Donor Specific IgG Antibodies to Class I & II test in Alappuzha?
Transplant candidates during pre‑transplant workup to detect preformed DSA and guide organ acceptance, desensitization, or allocation strategies.
Post‑transplant recipients for routine surveillance or when there is graft dysfunction, to detect de novo DSA and guide timely interventions.
More Information about DSA, Donor Specific IgG Antibodies to Class I & II test in Alappuzha
Donor-specific IgG antibodies are anti-HLA antibodies produced by a transplant recipient that specifically recognize the donor’s HLA Class I (A, B, C) and/or Class II (DR, DQ, DP) antigens, and they are a key biomarker for antibody-mediated rejection and graft injury.
Preformed DSA present before transplant can provoke hyperacute or early acute rejection and influence organ acceptance decisions, particularly if they cause a positive T-cell crossmatch.
