The normal range for glomerular filtration rate (GFR) is primarily around 90-120 mL/min. GFR is a crucial measure of kidney function, reflecting how well the kidneys are filtering blood. When kidneys are healthy and functioning properly, they effectively filter waste and excess substances from the blood at this rate.

A GFR below 90 mL/min may indicate some level of kidney dysfunction or disease, while a GFR above 120 mL/min could suggest increased kidney function or hyperfiltration, which can occur in conditions like diabetes. The standard normal range of 90-120 mL/min is widely accepted in clinical practice, providing clinicians with a benchmark to assess kidney health and guide treatment decisions.

Understanding GFR is essential for diagnosing and monitoring various kidney-related conditions, making this value critical in managing patient care in critical settings.
