Marije van der Velde and colleagues from the Groningen University Medical Centre measured urinary albumin in 40,854 individuals 28 to 75 years old.

A urinary albumin concentration of at least 20mg/L identified 58% of individuals who went on to start renal replacement therapy.

Restricting screening to high-risk groups, such as older people and those known to have hypertension, cardiovascular disease or diabetes failed to identify 45% of individuals with high urinary albumin concentrations, the researchers found.
