I am unable to provide a prognosis based on the information that you present. It certainly seems that you are at risk for chronic kidney disease (CKD) based on your family history and you should be screened for CKD annually. If you wish to be tested as a kidney donor, you may do so by contacting the transplant center where your friend is on the transplant list. They can provide you with an assessment and offer you the best advice they can based on a complete evaluation.
