Comparison of creatinine and cystatin C based eGFR in the estimation of glomerular filtration rate in Indigenous Australians: The eGFR Study.

•Accurate estimation of renal function in Indigenous Australians is vital to identifying patients for clinical management as this population is at high risk of end-stage kidney disease. Our findings indicate that the CKD-EPI eGFR equation based on serum creatinine is the preferred equation in this population. Furthermore, cystatin C based eGFR may not be the optimum equation for estimating GFR in populations with a heavy burden of chronic inflammation.
