Preferred collection container:
Specimen required:
2 mL serum or plasma; minimum 0.5 mL.

SPECIMEN PROCESSING
Specimen processing instructions:
Plasma: Centrifuge at 1100-2000 g for a minimum of 10 minutes. Serum: Allow to clot. Centrifuge at 1100-2000 g for a minimum of 10 minutes.

TEST DETAILS
Reference interval:
Less than 2 years: 0.1-0.4 mg/dL
2 years to <6 years: 0.2-0.5 mg/dL
6 years to <10 years: 0.3-0.6 mg/dL
10 years to <18 years: 0.4-1.0 mg/dL
Females 18 years or older: 0.5-1.0 mg/dL
Males 18 years or older: 0.6-1.2 mg/dL

This test provides a numerical eGFR for patients at risk for kidney disease at < 60 mL/min. Higher values are reported as “> 60 mL/min."
Additional information:
Estimated Glomerular Filtration Rate (eGFR) is calculated from the patient’s measured serum creatinine and the patient’s age and sex using the CKD-EPI formula recommended by the Kidney Disease Improving Global Outcomes (KDIGO) workgrup.
CPT code(s):
82565
Note: The billing party has sole responsibility for CPT coding.  Any questions regarding coding should be directed to the payer being billed.  The CPT codes provided by GML are based on AMA guidelines and are for informational purposes only.
Test includes:
Creatinine, estimated GFR.
Methodology:
Enzymatic
Synonyms:
Creatinine with eGFR, creatinine with GFR
Creatinine with estimated glomerular filtration rate
Clinical significance:
Serum creatinine is useful in the evaluation of kidney function and in monitoring renal dialysis. An estimated glomerular filtration rate (eGFR) will accompany all serum or plasma creatinine results.
