Below are the 5 stages in the CKD classification.
The CKD stage describes the severity of the chronic kidney disease – the higher the grade (stage), the worse the kidney function.
The 5 stages are based on something called ‘GFR’ (glomerular filtration rate). Normal GFR is 90-120 mls/min.
GFR is a blood test which estimates the level of function of the kidney – the higher the GFR, the better the kidney function (and therefore the lower stage of CKD that the patient will be in).
We will now go through the 5 CKD stages in more detail.
CKD1+2 – Risk factor for developing CKD (eGFR 60-120 mls/min; i.e. kidney function can be normal at these stages)
CKD3A+B – Mild CKD (eGFR 30-59 mls/min)
CKD4 – Moderate CKD (eGFR 15-29 mls/min)
Note. Some patients need to prepare for dialysis or transplant when their CKD becomes stage 4.
CKD5 – Severe CKD (kidney failure) (eGFR < 15 mls/min)
We have described the 5 stages of CKD. We hope it has been helpful.
