This protocol provides basic instructions for collecting and processing urine according to National Health and Nutrition Examination Survey (NHANES) methods. Creatinine concentration in a participant's morning urine sample is measured according to the Jaffe rate method. The protocol also lists reference ranges for healthy adults. The Diabetes Working Group recommends that the urine creatinine assay be performed on urine collected during a participant's morning void, but notes that a random sample is also acceptable.
