eGFR (Estimated Glomerular Filtration Rate) 88 mL/min/1.73m²: Is That Normal?

Is eGFR (Estimated Glomerular Filtration Rate) 88 mL/min/1.73m² Low, Normal, or High?

eGFR (Estimated Glomerular Filtration Rate) 88 mL/min/1.73m² might be considered within a healthy range for many individuals, particularly when viewed in isolation. This measurement reflects how well your kidneys are filtering waste from your body.

For most adults, an eGFR of 88 mL/min/1.73m² is generally seen as a sign of robust kidney function, though its full meaning is best understood in the context of your personal health profile.

Understanding this result is an excellent starting point for a conversation with your healthcare provider about your overall well-being and proactive health management.

An eGFR of 88 mL/min/1.73m² indicates a mildly reduced kidney function, categorizing it as early Stage 2 Chronic Kidney Disease (CKD). At this specific level, your kidneys are working slightly less efficiently than optimal, though it is very common for individuals to experience no noticeable symptoms whatsoever.

For many, an eGFR at 88 can reflect the natural process of aging, where kidney function gradually declines over decades, or it might be an early indicator of the cumulative effects of factors such as long-standing, mildly elevated blood pressure or subtle, early metabolic changes.

This reading is generally a gentle nudge towards vigilance rather than a sign of an acute crisis. To fully understand what this finding means for your health, your doctor will typically recommend a follow-up eGFR test to assess its stability or any trend, alongside a urine albumin-to-creatinine ratio (UACR) to check for protein leakage, a key marker of potential kidney damage.

Regular blood pressure monitoring and a thorough review of your medical history are also crucial steps. Critically, an eGFR of 88, especially if confirmed stable and without significant proteinuria, is often highly manageable through proactive lifestyle adjustments in diet, exercise, and blood pressure control.

For many, this level allows for a healthy, full life with appropriate ongoing monitoring, often preventing progression to more advanced kidney disease.

Hidden Risk of eGFR (Estimated Glomerular Filtration Rate) 88 mL/min/1.73m²
