Spot Urine Protein/Creatinine Ratio Testing at a Large University Medical Center: Evidence for Overuse of This Low-Value Diagnostic Test

摘要

Change in protein/creatinine ratio (PCR) testing over time in the Ohio State University Wexner Medical Center laboratories since 2013. The height of the bars indicates the total number of PCR testings (spot and 24-hour) each 2 months since 2013. The red bars show the spot PCR (UPC_Random), and the blue bars show the 24-hour PCR (UPCR24) utilization.
