What is the normal range for glomerular filtration rate?

The normal range for glomerular filtration rate (GFR) is essential for assessing kidney function. A GFR of 90-120 mL/min indicates that the kidneys are functioning properly and efficiently filtering blood. This range is typically used as a benchmark in clinical practice to evaluate renal health, with values falling below this range suggesting impaired kidney function.

When the GFR is maintained within this normal range, it reflects a well-hydrated state and adequate perfusion pressure in the kidneys, facilitating the optimal filtration of waste products from the bloodstream. Understanding this value is crucial for diagnosing kidney diseases and monitoring kidney health over time. Values outside this range, such as those above or below, may indicate various levels of kidney dysfunction or other health conditions that warrant further investigation.
