Interpretive Data
The CKD-EPI equation for non-African American individuals is used to calculate the estimated glomerular filtration rate (GFR). To estimate the GFR for African Americans, multiply the provided GFR result by 1.16.
The CKD-EPI equation is validated in individuals 18 years of age and older. However, the equation is less accurate in patients with extremes of muscle mass, restriction of dietary protein, ingestion of creatine, extra-renal metabolism of creatinine, or treatment with medications that affect renal tubular creatinine secretion.

GFR Categories in Chronic Kidney Disease (CKD) | ||
---|---|---|
GFR Category | GFR (mL/min/1.73 square meters) | Interpretation |
G1 | 90 or greater | Normal or high* |
G2 | 60-89 | Mild decrease* |
G3a | 45-59 | Mild to moderate decrease |
G3b | 30-44 | Moderate to severe decrease |
G4 | 15-29 | Severe decrease |
G5 | 14 or less | Kidney failure |
*In the absence of evidence of kidney damage, neither GFR category G1 nor G2 fulfill the criteria for CKD (Kidney Int Suppl 2013;3:1-150) |
Note
If a 24-hour urine collection is submitted, 24-hour calculations will not be performed. If 24-hour calculations are required, refer to test code 0050203 Albumin-Creatinine Ratio, Urine.
