Many of us here on this forum suffer from CKD as a chronic condition such as diabetes or any other illness that may be or has been long term, and consequently our kidney disease in many cases cannot be reversed, but can be manageable for a term. There are also others who may have had an injury or episode that results in an acute kidney impairment which perhaps can be reversed. At any event, there is a tendency to go online and seek answers from many sources, none of whom is your doctor and freak out to try to figure out why the sudden change. Many of us are vulnerable to immediate answers, but a nephrologist or NP or PA can be the best solution. I could go to 3 different labs in one day, and have 3 different eGFR results. In addition to eGFR, there is a Cystatin C lab test that also informs us of our current kidney condition. As you may know, kidney disease is long term and as such we follow the trend of our lab results, and respond accordingly with our doc or team of docs.
