What tests are required for kidney transplant compatibility testing?

Renal transplantation compatibility testing includes human leukocyte antigen (HLA) typing, panel-reactive antibody (PRA) testing, blood type compatibility assessment, infectious disease screening, and baseline organ function evaluation. These tests collectively assess the suitability of transplantation. If symptoms such as persistent fatigue, severe edema, or recurrent infections occur, prompt medical consultation and treatment are essential.

1. Human Leukocyte Antigen (HLA) Typing: This test compares the genetic compatibility between donor and recipient. Higher HLA matching reduces the risk of post-transplant rejection. The results serve as a core reference for compatibility assessment and directly influence transplant prognosis.

2. Panel-Reactive Antibody (PRA) Testing: This measures pre-existing sensitizing antibodies in the recipient’s bloodstream. Elevated PRA levels increase the risk of rejection after transplantation. PRA testing helps predict the likelihood of immune reactions post-transplant and assists clinicians in determining whether renal transplantation is appropriate.

3. Blood Type Compatibility Testing: This confirms whether the donor and recipient blood types meet compatibility criteria. ABO-compatible kidneys are strongly preferred. Incompatible blood types trigger intense immune responses and may render transplantation infeasible.

4. Infectious Disease Screening: This screens for hepatitis B, hepatitis C, HIV, syphilis, and other infectious diseases. It prevents pathogen transmission from donor to recipient via transplantation, safeguards the recipient’s postoperative health, and mitigates risks of cross-infection.

5. Baseline Organ Function Assessment: This evaluates the functional status of vital organs—including the heart, liver, and lungs—to determine whether the patient can safely undergo transplantation and subsequent immunosuppressive therapy, while also identifying significant comorbidities that could increase surgical risk.

In daily life, maintain a balanced, light diet and ensure adequate rest. Avoid exposure to infectious agents and sustain overall physical stability. Complete all preoperative evaluations as directed to ensure optimal preparation for the transplantation process.
