Urine Protein Creatinine Ratio

You should get a urine protein/creatinine ratio test if you have foamy urine, swelling in the face, feet, or ankles, or protein detected on a routine urine test. It is also recommended for people with diabetes, high blood pressure, lupus, or kidney disease, and for pregnant women with high blood pressure to check for preeclampsia.

No fasting is required for a urine protein/creatinine ratio test. Collect a first morning, midstream urine sample in a sterile container. Avoid strenuous exercise for 24 hours beforehand, and avoid testing during fever, urinary tract infection, or menstruation, as these can falsely raise protein levels. Inform your doctor about any medicines.

No, fasting is not required for a urine protein/creatinine ratio test. You can eat and drink normally before giving your sample. A first morning, midstream urine sample is preferred. Avoid strenuous exercise for 24 hours beforehand, and avoid testing during fever, infection, or menstruation for accurate results.
