Rey Complex figure testing before and after correction of severe kidney failure. This assessment captures multiple domains of cognitive function including memory, processing speed, and visuospatial construction ability. In this example the admission assessment, performed with a serum creatinine of 2,443 umol/L and blood urea of 67.6 mmol/L is compared to the discharge assessment (creatinine 629 umol/L, urea 17.8 mmol/L).
