eGFR (Estimated Glomerular Filtration Rate) 28 mL/min/1.73m²: Is That High?

Is eGFR (Estimated Glomerular Filtration Rate) 28 mL/min/1.73m² Low, Normal, or High?

eGFR (Estimated Glomerular Filtration Rate) 28 mL/min/1.73m² is a value that might be considered lower than what is typical for healthy kidney function. Seeing a number like this can naturally bring about questions and a desire for clear understanding.

It is not considered within the average range for most adults. Your eGFR gives insight into how well your kidneys are filtering waste from your system, and this specific reading indicates a need for closer attention and discussion with your healthcare team.

An eGFR of 28 mL/min/1.73m² signals a severely reduced kidney function, placing an individual squarely in Stage 4 Chronic Kidney Disease. At this critical level, the kidneys are struggling significantly to filter waste products from the blood, indicating a substantial loss of their normal capacity, which is typically 90-120 mL/min/1.73m².

This pronounced decline is often the cumulative result of prolonged and inadequately controlled conditions like severe hypertension or long-standing, unmanaged diabetes, which progressively damage the delicate filtering units of the kidneys over many years.

Consequently, a dedicated nephrology referral is immediate and essential. Further evaluations typically include comprehensive blood work to check electrolyte balance, phosphorus, calcium, parathyroid hormone levels, and a complete blood count for anemia, alongside urine tests to quantify proteinuria.

Renal ultrasound imaging is also common to assess kidney structure and look for obstructions. What many patients don't realize is that at an eGFR of 28, while reversing the damage is largely impossible, aggressive management focusing on slowing further progression and addressing complications like anemia, bone disease, and fluid retention becomes paramount.

This proactive approach aims to maintain quality of life and prepare for future treatment options, such as dialysis or kidney transplantation, well before an urgent crisis occurs.
