The decision to donate or receive an organ from a family member is a deeply personal one, and it is important to educate yourself about this decision, as there are many factors to consider. Testing of potential donors will typically occur under the direction of the transplant team and can begin whenever there is evidence of progressive kidney failure and/or end-stage renal disease in the child living with ARPKD. If the child is scheduled to undergo dialysis, the matching process can take place either before or following the procedure. Typically, the donor must be at least 18 years of age. When an individual is felt to be an excellent candidate, an extensive evaluation will take place, which can include a physical examination, laboratory and radiology tests, as well as a psychological assessment.
