Information collected by the ANZLKD Registry includes the medical tests performed prior to transplantation, the exact type of surgery performed and the donor's progress after the operation. Each year after the operation, the hospital which referred donors for transplantation will be asked to provide information about blood pressure, any new medical conditions which may have developed and results of a blood and urine test to check kidney function.  The Registry does not collect details about address, telephone number, medical insurance or non‐medical matters such as occupation, income etc.
