eGFR Normal Range — KDIGO Thresholds

New to reading lab reports? Start with our guide to reading a blood test report

This is an estimate of how much blood your kidneys clean each minute, so a higher number is usually better.

eGFR turns a lab value into an easy-to-follow score for your filtering. It is worked out from a formula, giving you a single figure you can watch across visits.

Also known as: Estimated Glomerular Filtration Rate, GFR, eGFR CKD-EPI, Kidney Filtration Rate

Higher is generally better

A higher number here generally means your kidneys are filtering waste from the blood better.

What is eGFR?

This is a calculated estimate of the volume of blood the kidneys filter each minute. A formula combines your creatinine level with your age and sex to produce the figure.

Why is eGFR tested?

You have this test to check your overall kidney filtering and to follow your kidney health over time.

What is a normal eGFR range?

India
No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
Global
≥60 mL/min/1.73m² (normal kidney function in adults)

Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does a eGFR of 15 mean?

Find your eGFR result in the table below, then read the band it falls into. Each band names the guideline body it comes from. Always compare against the range printed on your own report.

eGFR Below 15 mL/min — Kidney failure range (G5)

If your result is 5, 10, 14 or anywhere in this band: This suggests the kidneys are filtering very little. It is worth discussing with your doctor promptly, alongside your other kidney results.

Worth asking your doctor

  • What do these kidney numbers mean together for me?
  • What are the next steps, and how soon?

eGFR 15–30 mL/min — Severely reduced (G4)

If your result is 15, 20, 25, 29 or anywhere in this band: This points to a large drop in kidney filtering. It is read with your urine tests and repeated over time before conclusions.

Worth asking your doctor

  • How was this figure worked out for me?
  • What checks help understand my kidney health?

eGFR 30–45 mL/min — Moderate–severe reduction (G3b)

If your result is 30, 35, 40, 44 or anywhere in this band: This suggests a moderate drop in filtering. A single value is not a diagnosis; kidney stage needs repeat testing over months.

Worth asking your doctor

  • Should this be repeated before reading too much into it?
  • What can I do to look after my kidneys?

eGFR 45–60 mL/min — Mild–moderate reduction (G3a)

If your result is 45, 50, 55, 59 or anywhere in this band: This is somewhat below the usual range. It is common with age and is read alongside your urine tests and blood pressure.

Worth asking your doctor

  • Is this expected for my age, or worth watching?
  • When should it be checked again?

eGFR 60–90 mL/min — Mildly reduced (G2)

If your result is 60, 70, 80, 89 or anywhere in this band: This is only slightly below the top range. On its own, without other signs, it is often not a concern.

Worth asking your doctor

  • Does this need any follow-up for me?

eGFR 90 mL/min and above — Normal or high (G1)

If your result is 90, 100, 110, 120 or anywhere in this band: This suggests the kidneys are filtering well. Kidney health is still read with your urine tests, not this number alone.

Worth asking your doctor

  • Is my kidney filtering normal for me?

What does a high eGFR result mean?

A higher eGFR usually reflects well-working kidneys. With this test, higher is generally better.

What does a low eGFR result mean?

A lower eGFR can mean your kidneys are filtering less well. It is worth discussing with your doctor.

What can affect your eGFR result?

  • Your creatinine level
  • Age
  • Sex
  • Muscle mass
  • Ancestry, which some older equations adjust for

Questions to ask your doctor

About this result

  • What does my eGFR result mean for me specifically, given my age and health?
  • For eGFR, higher is generally considered better — where does my result sit, and is that reassuring?
