Which GFR level indicates mild kidney function loss?

The answer indicating a GFR level of 60-89 mL/min/1.73m² reflects mild kidney function loss in the classification of chronic kidney disease (CKD). The glomerular filtration rate (GFR) is a critical metric used to assess how well the kidneys are functioning.

In clinical practice, a GFR of 60-89 mL/min/1.73m² is generally associated with stage 2 chronic kidney disease, where there is mild reduction in kidney function. Individuals within this range may not experience significant symptoms or complications and often may be managed with lifestyle changes or monitoring rather than intensive treatment.

Other ranges denote more significant loss of kidney function, where GFR levels drop below 60 mL/min/1.73m², indicating moderate to severe kidney disease. Understanding these ranges is key for healthcare providers in determining the stage of kidney disease, assessing patient risk, and guiding treatment decisions.
