Kidney Disease
Stages
Chronic kidney disease (CKD) is divided into 5 stages based on the level of kidney function. Stages are determined through certain tests performed by your doctor, including a test used to calculate estimated glomerular filtration rate (eGFR), which measures how well your kidneys are cleaning your blood. Kidney disease is a progressive disease, meaning that kidney function can continue to decline over time, eventually resulting in kidney failure.
While there is typically no cure for CKD, there are treatments that can help. Getting tested is important—with early diagnosis and treatment, you may be able to slow progression and keep your kidneys working longer.
