Urine Protein Creatinine Ratio Test Overview

The urine protein creatinine ratio test is conducted to identify the amount of protein in the urine with creatinine levels. The test allows monitoring kidney function and aids in the detection and diagnosis of early kidney disease. In general, the normal range of protein in urine should be less than 150ml per day. However, any deficiency or excess from the normal range can invite kidney-related issues.

Since the UPCR test measures both creatinine and protein levels, you only need to give one urine sample. It is the best alternative to multiple test sample collections. The presence of albumin in the urine indicates kidney disease, especially in individuals with diabetes or high blood pressure.

Why is Urine Protein Creatinine Ratio Prescribed?

If your doctor suspects kidney disease, they will likely recommend a urine protein-to-creatinine ratio (UPCR) test. This test helps detect high levels of protein in the urine, a condition known as proteinuria, and is considered one of the most reliable tools for diagnosing kidney-related conditions.

A UPCR test may be necessary in the following situations:

●       To specifically evaluate kidney function or to screen for proteinuria.

●       If you show signs of preeclampsia during pregnancy.

●       To help diagnose or monitor kidney disorders, especially if you have abnormal serum creatinine levels or other related symptoms.

Components of Urine Protein Creatinine Ratio

The components of Urine Protein Creatinine Ratio test differ according to the ranges.

●       The normal range for microalbumin creatinine ratio is less than 30 mg/gm.

●       Microalbumin creatinine ratio: 30-299 mg/gm indicates microalbuminuria. A result higher than 300 mg/gm indicates clinical albuminuria.

Procedure and Perquisites of Urine Protein Creatinine Ratio

There is no special procedure involved in the UPCR test. Once you've provided a urine sample, your healthcare provider may test using essential tools and check for any inconvenience. The lab will measure the levels of protein and creatinine in the urine.

You need to have clean small container to collect the urine sample. Ensure you check with the doctor to know the right time to collect the urine. Usually, morning urine collection is recommended.
