eGFR (CKD-EPI 2009)
Estimated GFR — CKD-EPI 2009 creatinine equation without the ethnicity adjustment (as used by UK laboratories).
What it is for
CKD staging by GFR category (NICE NG203). NICE NG203 recommends the CKD-EPI creatinine equation without an ethnicity adjustment; a UK Kidney Association-led taskforce (with the ACB and UK NEQAS) advises the 2009 equation without the ethnicity factor, and the 2021 version has not been adopted in the UK. Your lab report remains the reference value. For drug dosing, check the SPC.
