What does a GFR of 42 mean?

A Glomerular Filtration Rate (GFR) of 42 mL/min indicates moderate to severe kidney dysfunction. GFR measures how well the kidneys are filtering waste from the blood, with normal values typically above 90 mL/min. A GFR of 42 suggests that the kidneys are not functioning adequately, which may necessitate further evaluation and potential treatment, including lifestyle changes or medications to protect kidney function. It's important to consult a healthcare provider for a comprehensive assessment and management plan.
