Which GFR level indicates moderate to severe kidney function loss?

A Glomerular Filtration Rate (GFR) level of 30-45 mL/min/1.73m² indicates moderate to severe loss of kidney function. GFR is a crucial measure of kidney health, specifically assessing how well the kidneys are filtering waste from the blood. In general, normal kidney function is indicated by a GFR of 90 mL/min/1.73m² or more.

As the GFR value decreases, it reflects increasing degrees of kidney impairment. A GFR between 30-45 indicates that the kidneys are significantly less efficient at filtering blood, which can lead to various complications and necessitate medical intervention. This range is recognized in clinical guidelines as part of the classification of chronic kidney disease (CKD), where stages are defined based on GFR levels.

GFR levels below 30 mL/min/1.73m² (notably in the lower range of values provided) reflect more severe kidney function loss and indicate end-stage kidney disease, requiring more intensive management such as dialysis or transplantation. Thus, the range of 30-45 mL/min/1.73m² is accurately associated with moderate to severe kidney function loss, underlining the importance of monitoring these values
