Even Low Levels of Albumin in Urine Tied to Worsened Kidney Disease

For decades, researchers characterized normal albuminuria as a urine albumin-creatinine ratio of less than 30 mg/g. That has led some clinicians to believe that patients with lower ratios don’t need additional treatment. But a new study in Annals of Internal Medicine challenges that assumption by showing that even low levels of albuminuria are a risk factor for kidney failure in people with chronic kidney disease.
