What is the normal range for eGFR(CKD-EPI) in and adult male blood?

For an adult male, the normal range for eGFR (CKD-EPI equation) is:

90 mL/min/1.73 m² or higher → considered normal kidney function

eGFR ranges explained:

≥ 90: Normal (if no other signs of kidney disease)

60–89: Mildly reduced (can be normal with aging, usually monitored)

30–59: Moderate kidney dysfunction

15–29: Severe kidney dysfunction

< 15: Kidney failure

Most importantly, eGFR naturally declines with age. A slightly lower value in older adults may still be acceptable if there are no symptoms or other abnormal kidney markers.

This test should always be interpreted by a doctor along with creatinine levels, urine tests, symptoms, and medical history.
