When to Seek Prompt Care

Symptoms such as sudden swelling in hands or feet, foamy urine, or significant changes in urination patterns should prompt a call to your clinician. No common urgent flag from this test alone.

What It Measures

This test checks the amount of protein in your pee. It compares it to a waste product called creatinine. This helps doctors see how well your kidneys are doing their job.

Why It's Ordered

Your doctor orders this test for a few reasons. It can be part of your regular check-up. They might also order it to check how well your kidneys are working. If you have health problems like diabetes or high blood pressure, these can affect your kidneys. This test helps find early signs of kidney issues.

Reference Range

Reference ranges for UPCR can vary by laboratory, and interpretation may depend on factors such as age, sex, pregnancy status, and clinical context.
