In 2012 guidelines were published in Belgium for the recognition of chronic kidney disease (CKD) by general practitioners. This takes into account age and the change in GFR over time.
Parameters:
(1) current estimated GFR (eGFR) in mL per min per 1.73 square meter
(2) age in years
(3) urine protein excretion (albumin to creatinine ratio in mg/g, protein to creatinine ratio in mg/g)
(4) delta eGFR over past 5 years
delta in eGFR over 5 years =
= (eGFR 5 years ago) - (current eGFR)
