What does a GFR below 60 indicate?

A Glomerular Filtration Rate (GFR) below 60 indicates possible kidney disease. GFR is a test that measures how well the kidneys are filtering blood. Normal GFR values typically range from 90 to 120 mL/min. When the GFR drops below 60 mL/min, it suggests that the kidneys are not functioning at optimal levels and that there may be some level of kidney impairment. This reduction in function can be indicative of chronic kidney disease or other kidney-related issues that require further investigation.

While a GFR lower than 60 does not automatically indicate kidney failure, it is a signal for healthcare providers to monitor and assess kidney function further. Early detection of potential kidney disease can lead to interventions that might slow the progression of the disease. In contrast, GFR levels in the normal range or signs of high hydration would not trigger the same level of concern regarding kidney health.
