What should I do if my eGFR is 90?

Recheck yearly if you have diabetes, hypertension, or family history Check a urine albumin-creatinine ratio once to be thorough

eGFR — Stage G1 — Normal

eGFR 90 mL/min/1.73mÂ²: What It Means

Classification: Stage G1 — Normal

eGFR 90 or above is normal kidney function. CKD is only diagnosed at this level if there are other damage markers (albuminuria, blood in urine, abnormal imaging).

What can cause this?

Healthy kidneys

About the eGFR test

Estimated glomerular filtration rate — the best overall measure of kidney function. It is calculated from creatinine, age, and sex (CKD-EPI 2021 equation) and used to stage chronic kidney disease.

Calculated from a serum creatinine blood test. No extra sample needed — labs report eGFR automatically with any creatinine.

Reference: KDIGO CKD classification; CKD-EPI 2021 equation (NEJM 2021) • Normal range: â‰¥90 mL/min/1.73mÂ² (declines with age)
