eGFR
The estimated glomerular filtration rate (eGFR) is a calculation that estimates how well your kidneys filter waste from your blood. It is the best overall measure of kidney function.
Category: Metabolic Panel
Also known as: gfr, egfr, estimated gfr, glomerular filtration rate, estimated glomerular filtration rate
Reference range: 90–120 mL/min/1.73m² (Source: ABIM)
Standard unit: mL/min/1.73m²
High values may indicate
High eGFR values generally indicate normal, healthy kidney function. Values above the reference range are typically not a clinical concern.
Low values may indicate
Low eGFR values may indicate kidney disease. An eGFR below 60 for three or more months suggests chronic kidney disease, and below 15 indicates kidney failure.
Frequently asked questions
- What is a normal eGFR level?
- A typical reference range for eGFR is 90–120 mL/min/1.73m² (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is eGFR measured in?
- eGFR is most commonly reported in mL/min/1.73m². Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do eGFR reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track eGFR over time?
- Yes. Upload results from any lab and BloodId charts your eGFR over time against its reference range, so you can see whether the trend is rising, falling, or stable.
