Questions about this test
Why use a protein creatinine ratio instead of a 24-hour urine test?
The ratio uses a single sample and corrects for how concentrated your urine is, so it is easier than collecting urine for 24 hours. It gives a good estimate of daily protein loss in most situations.
Why is this test done in pregnancy?
If your blood pressure is high in pregnancy, protein in the urine can be a sign of preeclampsia. The protein creatinine ratio is a common way to check this.
Can a urine infection raise the result?
Yes. A urine infection, fever or heavy exercise can raise urine protein for a short time. Your doctor may repeat the test once these have settled.
