Your estimated glomerular filtration rate (eGFR) is 20 and this would be consistent with Stage 4 chronic kidney disease (CKD). When your eGFR is less than 20 milliliters per minute per 1.73 meters squared, you could be eligible to apply for the kidney transplant list. You would have to be evaluated by a transplant center once your eGFR stays less than 20 for more than three months. You should continue to have urine and blood testing for your CKD every six months and consult with your physician every six months for proper management. You should not smoke and you should try to maintain a healthy low salt diet and keep your weight in a healthy range. If you are doing all these things, then you are doing all you can for your kidneys.
