Frequently Asked Questions
Is fasting required for eGFR test?
No, fasting is not required. eGFR is calculated from serum creatinine and can be measured at any time of day.
What does eGFR measure?
eGFR estimates how much blood passes through the glomeruli each minute, reflecting overall kidney filtering capacity. It is expressed in mL/min/1.73m².
How is eGFR interpreted?
Normal eGFR is 90 or above. Values between 60-89 may indicate early kidney changes, while below 60 for three months or more suggests chronic kidney disease. Below 15 indicates kidney failure requiring dialysis or transplant.
Can medications affect eGFR results?
Yes. Certain drugs like NSAIDs, ACE inhibitors, and some antibiotics can alter kidney function and creatinine levels, potentially affecting eGFR. Inform your doctor about all medications before testing.
Does dehydration impact eGFR?
Yes, dehydration can temporarily reduce kidney filtration and raise creatinine levels, leading to a falsely low eGFR. Stay well-hydrated before sample collection for accurate results.
