EGFR is 59 L what does this mean?

An estimated glomerular filtration rate (eGFR) of 59 mL/min indicates that kidney function is moderately impaired, typically classified as stage 3 chronic kidney disease (CKD). This means the kidneys are not filtering blood effectively, which can lead to a buildup of waste and fluids in the body. It is important to monitor kidney health and consult a healthcare professional for further evaluation and management.
