Twenty-four-hour urine protein quantification remains the reference standard for evaluating proteinuria. A complete and properly timed collection provides accurate measurement of daily protein loss, essential for diagnosing and staging kidney disease.
This test is used in evaluation of suspected kidney disease, monitoring of nephrotic syndrome, assessment of preeclampsia, and following response to treatment in glomerular diseases. Patient education about proper collection technique is critical. Sample type is a 24-hour urine collection.
