What is the normal glomerular filtration rate (GFR) for adults?

The normal glomerular filtration rate (GFR) for adults is typically considered to be in the range of 90-120 mL/min/1.73 m². This value serves as a crucial marker for kidney function. GFR is a measure of how effectively the kidneys filter blood, which is essential for maintaining homeostasis and overall health. Values within this range indicate normal kidney function, while deviations may suggest either decreased renal function or other underlying health issues.

In understanding the concept of GFR, it is important to recognize that it is influenced by various factors including age, sex, and body surface area, which is why it is standardized to a body surface area of 1.73 m². Knowing the normal range helps healthcare providers assess kidney function in patients, diagnose potential renal diseases, and make decisions regarding treatment protocols.
