Collection Information:  
Test Schedule:  
Turnaround time from when specimen
is received in testing laboratory:
Reference Range: For patientís under 18 years of age eGFRís are reported as: eGFR calculation is not available for patients under 18 years of age.

eGFR: < 15 mL/min/1.73 m2
Consistent with kidney failure

eGFR: 15-29 mL/min/1.73 m2
Consistent with severe chronic kidney disease

eGFR: 30-44 mL/min/1.73 m2
Moderate to severe decreased kidney function is consistent with chronic kidney disease if confirmed over 3 months

eGFR: 45-59 mL/min/1.73 m2
Mild to moderate decreased kidney function is consistent with chronic kidney disease if confirmed over 3 months.

eGFR: 60-89 mL/min/1.73 m2
Consistent with mildly decreased kidney function, however, in the absence of other evidence of kidney disease, eGFR values in this range do not fulfill the KDIGO criteria for chronic kidney disease.
Interpret results in concert with ACR measurement.

eGFR: ≥ 90 mL/min/1.73 m2
Normal eGFR
Effective Date: 2016-01-04
Revised Date:  
Critical Value:  
Interpretive Comments:  
Special Processing:  
Comments: eGFR is calculated using the CKD-EPI 2009 equation. Multiply eGFR by 1.159 for patients of African descent.
Results for eGFR should be interpreted in concert with urine albumin creatinine ratio (ACR). eGFR is not valid for extreme muscle mass, pregnancy, drug dosing and acute kidney injury and not normalized for body surface area
Method of Analysis: See Comments
Critical Information Required: Serum creatinine, age, gender, race
