A normal eGFR for adults is greater than 90 mL/min/1.73m2, according to the National Kidney Foundation. Persons with a normal GFR may have CKD if they have persistent proteinuria or hematuria of renal origin. A GFR below 60 may mean kidney disease.

A normal range for adults with normal kidney function is 0.8 to 1.3 milligrams per deciliter for males and 0.6 to 1.1 milligram per deciliter for females. All Rights Reserved. The normal serum creatinine does not necessarily reflect a normal GFR for a patient. Glomerular Filtration Rate (GFR) is the rate in which blood moves through miniscule kidney filters. However, if the eGFR blood test range is below 60, it reveals the possibility of a kidney disease.

Those with GFR results below 15 mL/min are a sign of Kidney Failure. eGFR 15-29, severe kidney damage Kidney function blood test normal range for serum creatinine is 0.8 to 1.2 mg/dl in males and 0.6 to 0.9 mg/dl in females. These filters help remove waste and excess fluid from the blood. A GFR of 15 or lower may mean kidney failure. A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval).

For children under the age of 18, the eGFR blood test can still produce accurate results, but the calculation formulas are a little different than they are with adults. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2) until 2 years of age in both sexes, and then it progressively decreases. I am 71 next month. Interpretation.
