What is urine PC ratio test?

The urine protein-to-creatinine (PC) ratio test is a diagnostic test used to assess kidney function by measuring the amount of protein and creatinine in a urine sample. It helps to determine if there is an abnormal level of protein in the urine, which can indicate kidney damage or disease. The test is often preferred over a 24-hour urine collection because it is quicker and easier to perform. A higher ratio suggests greater proteinuria, which may require further evaluation.
