Ethnic differences in creatinine kinetics in a New Zealand end-stage kidney disease cohort.

Background: Recent data have suggested that glomerular filtration rate (GFR) is better predicted in New Zealand (NZ) Māori and Pacific People using the equations for Black people that predict higher GFR for any given serum creatinine. We hypothesized that this might be due to a higher rate of creatinine generation in NZ Māori and Pacific People.

Aim: To compare creatinine kinetics between different ethnic groups in a cohort of NZ peritoneal dialysis patients.
