A random urine sample can quickly identify the presence of significant proteinuria, though quantitative assessment requires either a 24-hour collection or correction for urine concentration using creatinine. Persistent proteinuria suggests kidney disease and warrants further evaluation.
This test is used in initial screening for kidney disease, evaluation of urinary symptoms, and follow-up of patients with known kidney conditions. When more precise quantification is needed, protein/creatinine ratio or 24-hour collection is preferred. Sample type is a random urine specimen.
