Is an eGFR of 92 Outstanding?
An eGFR of 92 mL/min/1.73 m² is normal and represents healthy kidney function, falling within Stage G1 (≥90 mL/min/1.73 m²), which is the highest kidney function category. 1
Understanding Your eGFR Value
- Your eGFR of 92 places you in Stage G1, which is defined as eGFR ≥90 mL/min/1.73 m² and represents normal or high kidney function 1
- This value falls well within the healthy adult range of 63.5-139.2 mL/min/1.73 m² depending on the calculation method used 2, 3
- You do not have chronic kidney disease (CKD) based on eGFR alone, as CKD requires either eGFR <60 mL/min/1.73 m² OR evidence of kidney damage (such as albuminuria ≥30 mg/g) persisting for at least 3 months 4
Clinical Context and Implications
For medication dosing and medical decisions, your kidney function is considered normal:
- No medication dose adjustments are needed at this eGFR level, as modifications are only considered when eGFR falls below 60 mL/min/1.73 m² 5
- You are not at risk for kidney failure requiring nephrology referral, which is considered only when eGFR drops below 30 mL/min/1.73 m² or when 5-year kidney failure risk exceeds 3-5% 5
From a cardiovascular perspective, higher eGFR values like yours are associated with better outcomes:
- Higher eGFR within the normal range correlates with fewer cardiovascular events, particularly in the 100-130 mL/min/1.73 m² range, though your value of 92 still represents good kidney function 6
Important Caveats
eGFR alone does not tell the complete story:
- Stage G1 CKD can still exist if you have evidence of kidney damage (albuminuria, blood in urine, structural abnormalities) despite normal eGFR 1, 4
- Annual screening is recommended if you have diabetes or hypertension, including urine albumin-to-creatinine ratio (UACR) testing, as albuminuria independently predicts cardiovascular and kidney disease risk even with normal eGFR 1, 4
- eGFR is an estimate, not a direct measurement, and can be affected by factors like muscle mass, age, and the specific equation used 7, 8
Bottom line: Your eGFR of 92 is excellent and indicates normal kidney function, but ensure you have no evidence of kidney damage through urine testing if you have risk factors like diabetes or hypertension 1, 4
