This study evaluated three equations for estimating glomerular filtration rate using creatinine alone, cystatin C alone or both. The mean GFR was 68 ml/min in the development set and 70 ml/min in the validation set. In the validation set, the creatinine-cystatin C equation performed better than equations using either marker alone. However, the routine use of this equation is limited by the availability of cystatin C assays.
