Diagnostic test: A 24-hour urine collection is a simple diagnostic procedure that measures the components of urine. The test is noninvasive (the skin is not pierced), and is used to assess kidney (renal) function. Specifically the amount of creatinine excreted is measured to get an estimate of the glomerular filtration rate (gfr).
