What does a GFR of 28 mean?

A Glomerular Filtration Rate (GFR) of 28 mL/min indicates significantly reduced kidney function, typically classified as stage 4 chronic kidney disease (CKD). This level of GFR suggests that the kidneys are functioning at less than 25% of their normal capacity, which can lead to a buildup of waste products in the blood. Patients with such a low GFR often require close monitoring and may need to discuss treatment options, including potential dialysis or kidney transplantation, with their healthcare provider.
