In the liver transplantation process, it is essential that the blood groups of the recipient and donor are compatible. Following blood group compatibility, the potential donor must undergo a detailed evaluation process. This process comprises social, psychological, and comprehensive medical examinations. The medical evaluation phase includes various tests such as blood and urine analyses, infectious disease screenings, radiological imaging, and consultations from relevant medical departments like cardiology and pulmonology. Furthermore, several critical factors, such as the amount of liver tissue required by the recipient, the donor candidate's general health, the surgical feasibility of dividing their liver appropriately, and the structure of their bile ducts, play a decisive role in the successful outcome of the transplant operation.
