What GFR level is considered normal?

A Glomerular Filtration Rate (GFR) level of 60 or higher is considered normal as it indicates that the kidneys are functioning properly and effectively filtering waste from the blood. GFR is a critical measure used to assess kidney function, and a reading of 60 mL/min or higher suggests that the kidneys are adequately filtering blood and maintaining normal function.

When GFR falls below 60, it may indicate the presence of chronic kidney disease (CKD). Specifically, a GFR between 30 and 59 indicates moderate kidney impairment, while values below 30 indicate severe impairment. Levels below 15 signify kidney failure or end-stage renal disease, necessitating interventions such as dialysis or transplantation.

In summary, a GFR of 60 or higher is the threshold that signifies normal kidney function, making it an essential parameter for evaluating renal health.
