The eGFR test is a key marker for evaluating kidney function, particularly in individuals with or at risk for chronic kidney disease (CKD). It estimates how efficiently the kidneys filter waste and excess fluid from the blood.
- Normal eGFR: 90 mL/min/1.73m² or higher. This range indicates healthy kidney function, where the kidneys are effectively filtering waste.
- Mildly Decreased eGFR: 60-89 mL/min/1.73m². This can be normal for older adults or could suggest early kidney issues, especially if paired with other signs of kidney damage.
- Moderately Decreased eGFR: 30-59 mL/min/1.73m². This suggests moderate CKD, where kidney function is impaired, requiring lifestyle changes and possible treatment.
- Severely Decreased eGFR: 15-29 mL/min/1.73m². This stage indicates advanced kidney damage, often requiring more intensive treatment to slow CKD progression.
- Kidney Failure (End-Stage Renal Disease): Below 15 mL/min/1.73m². At this stage, the kidneys can no longer adequately filter waste, and dialysis or a kidney transplant may be required.
Why is eGFR important for CKD?
- Early Detection: Regular eGFR testing helps detect CKD in its early stages, allowing for timely interventions.
- Monitoring Progression: For patients with known CKD, frequent testing tracks disease progression and adjusts treatment plans as needed.
- Managing Risk Factors: A low eGFR may prompt changes in diet, medication, or lifestyle to protect kidney health.
When to Seek Medical Advice:
If your eGFR is consistently below 60 or drops significantly, consult your doctor to evaluate your kidney function and discuss treatment options.
Recommended Tests:
- Creatinine Test:
Since eGFR is calculated based on creatinine levels, monitoring creatinine provides direct insight into kidney function.
Creatinine Test - Albumin-to-Creatinine Ratio (ACR) Test:
This test helps detect early signs of kidney damage by measuring protein in urine. It complements the eGFR test for a comprehensive kidney health assessment.
