The Protein/Creatinine Ratio test is performed to screen for excessive proteins excreted in the urine to monitor kidney function. Creatinine protein is a byproduct of muscle metabolism and is normally released into the urine at a constant rate. The Protein/Creatinine ratio test is done to monitor kidney functioning, to check for damage in case of the condition affecting the kidney, and efficacy of treatment on already affected kidneys. Proteinuria in the urine helps identification of early kidney damage which is almost always asymptomatic. Persistent and/or an increased amount of protein in the urine may indicate kidney damage or disease. The goal of this test is to detect kidney disease and damage early to minimize the damage and prolong kidney function.
The test helps in evaluating the extent of protein loss in the urine and is often used to assess kidney function and diagnose conditions such as kidney damage, kidney disease, or other underlying health issues. It is particularly useful in the detection of proteinuria, which is the presence of abnormally high levels of protein in the urine.
To perform the test, a single urine sample is collected, typically in the morning. The sample is then sent to a laboratory for analysis. The protein/creatinine ratio is calculated by dividing the amount of protein in the urine by the amount of creatinine.
A normal protein/creatinine ratio is typically less than 0.2 grams of protein per gram of creatinine for a random urine sample. Elevated ratios may suggest proteinuria, indicating potential kidney damage or disease.
