Table 2.
Name of equation | Comments |
---|---|
MDRD study | Less accurate at eGFR >60 ml/min/1.73 m2 and older age |
CockroftGault | Decreased accuracy at lower levels of CKD |
CKD-EPI Scr | Overestimates CKD in older individuals |
CKD-EPI cystatin C | Better for older individuals and those with reduced muscle mass |
CKD-EPI Cr-cystatin C | Performs better than all above in estimating GFR. Better in elderly |
Berlin initiative study (BIS-1) | Reliable for use in the elderly with stage 1–3 CKD, CKD-EPI be used in stages CKD 4–5 |
CKD: Chronic kidney disease; CKD-EPI: Chronic kidney disease epidemiology collaboration; eGFR: Estimated glomerular filtration rate; MDRD: Modification of diet in renal disease; Scr: Serum creatinine.
