 The investigators intend to perform a large prospective study looking at the predictability of the random urine protein-to-creatinine ratio compared to the gold standard 24-hour urine protein collection. Furthermore, the investigators plan to investigate whether analysis of proteinuria at shorter time intervals 4 and 8 hours within the overall 24-hour collection period is predictive of the 24-hour sample. Lastly, the investigators plan to determine whether a combination of the random test with a shorter collection interval is comparable to the 24-hour collection.
