Name

 EGFR

Alternative name/Profile

 Estimated Glomerular Filtration Rate

Department

 Biochemistry

Investigation

 Estimated GFR (eGFR) is a calculation primarily based on creatinine levels, age and sex to give an estimate of the glomerular filtration rate as an indication of kidney function. It can be used as an index in the classification (staging) of Chronic Kidney Disease. An eGFR is calculated for every serum creatinine measured in our lab.

Specimen type

 Serum

Sample type

Sample container & volume

 5ml - Red Tube

Frequency of analysis

 Daily

Turnaround time

 1 day

Availability

 Daily, throughout 24 hours

Notes

eGFR calculated by 4V-MDRD formula. Multiply result by factor of 1.21 if patient of African ethnicity.

Results must be interpreted in accordance with Irish CKD Guidlines (www.nephrology.ie)
The diagnosis of  CKD is entirely based on eGFR once value is less than 60 ml/min/1.73 m². 

CKD stages 1 and 2 require other clinical features to appropriately apply CKD label.

Results are not applicable to subjects :

  1. If age less than 18 years.      
  2. With extremes of body surface area and muscle mass.                        
  3. With acute renal impairment   
  4. Pregnancy.

Note : eGFR not yet validated in patients over 80 years
