Estimated Glomerular Filtration Rate

Message
INCLUDED IN MET10, CMP, RENAL PANELS


Test Code
EGFR1, EGFR2


Alias/See Also
GFR, EGFR, Glomerular Filtraion Rate, EGFR1, EGFR2
 


Reference Range
Calculation-Using the MDRD Equation:

GFR(mL/min/1.73 m2) = 175 x (Scr)-1.154 x (Age)-0.203 x (0.742 if female) x (1.210 if African American)

                          “Scr” is serum creatinine in mg/dL.


EGFR1 (Non-African American)
EGFR2 (African American)
GFR is estimated using the MDRD equation recommended by the National Kidney Disease Education Program.

Estimated GFR Interpretive Information:  (EGFR/mL/min/1.73m2)
  •     >90:  Normal - if no other evidence of kidney disease present.  Chronic Kidney Disease Stage 1 - if there is evidence of kidney disease present such as proteinuria, hematuria,  genetic kidney disease, or structural abnormality.
  •   60-89:  Chronic Kidney Disease Stage 2 (Mild)
  •   30-59:  Chronic Kidney Disease Stage 3 (Moderate)
  •   15-29:  Chronic Kidney Disease Stage 4 (Severe)
  •     <15:  Chronic Kidney Disease Stage 5 (End Stage, Kidney Failure)
* GFR must be <60 mL/min/1.73m2 for at least 3 months to meet the definition of Chronic Kidney Disease.
