creatinine peptide ratio FAQ

A UPCR test result of 2.5 or more is a sign of very severe proteinuria.

There’s no specific preparation required for a UPCR test. But it’s important to tell the doctor if you’re menstruating or have bleeding hemorrhoids, as blood and other discharge may affect the results of your urine sample.

A high protein-to-creatinine ratio may be a sign of an underlying health condition that could affect your kidney function, such as diabetes, kidney disease, and heart disease.

Some ways to help lower your creatinine levels may include drinking more water, limiting protein and sodium intake, avoiding creatine supplements, and increasing fiber intake.

A result on the UPCR test that’s higher than normal may be an indication of kidney disease. Kidney disease is often caused by the effects that other health conditions have on your kidneys,

After providing your urine sample, the doctor may analyze it there using a dipstick. In this case, they will provide your results within a few minutes. In other cases, they will send your urine sample to a laboratory for a more detailed analysis. In this case, your doctor may take up to 10 days to contact you with the test results. If the values of your UPCR test are outside of the normal range, a doctor may want to order additional tests to evaluate your kidney function. This may include:

Creatine levels do not necessarily align with chronic kidney disease stages. However, a person with stage 2 chronic kidney disease typically has an eFGR test result of 60–89.

The 5 stages of chronic kidney disease can demonstrate a person's level of kidney damage. The higher the stage, the more damage a person's kidneys have. However, creatine levels do not necessarily determine a person's level of kidney failure. A person with "normal" creatine levels can still have kidney damage.

Creatinine levels above 1.2 milligrams per deciliter (mg/dl) for males and 1.0 mg/dl for females are considered high. However, a person should not be alarmed by their creatinine level result. This test alone does not always provide a full picture of a person's kidney health. People should follow up with a healthcare professional if their creatinine is elevated for a full evaluation.

High creatine levels can indicate kidney failure. However, a person with typical creatine levels can still have kidney disease. Doctors may calculate a person's estimated glomerular filtration rate (eGFR) to get a more accurate picture of kidney function.
