OVERVIEW
In this test, the amount of protein in a urine sample is measured along with urine creatinine and
reported as the ratio of urine protein to creatinine (UPCR). Urine protein/creatinine test detects the
presence of protein into the urine. Normal urine protein elimination is less than 150 mg/day and less
than 30 mg of albumin/day.
WHAT DOES THE TEST MEASURE?
This test measures the presence of protein in the urine, the presence of protein in the urine is known as
proteinuria. Proteinuria is frequently seen in chronic conditions, such as diabetes and hypertension. The
increased amount of protein in the urine reflects an increase in kidney damage.
FREQUENTLY ASKED QUESTIONS:
How is this test performed?
This test is performed on a urine sample.
What are the risks associated with this test?
There is no significant risk associated with this test.
Is there any preparation required before the test?
No preparation required before this test.
INTERPRETATION OF THE RESULT:
- A negative test result means that there is no detectable amount of protein in the urine at the time of testing.
- Protein detected in a random urine sample may be due to an infection, medication, vigorous exercise, pregnancy, diet, cold exposure, or emotional or physical stress. Testing should be repeated after these conditions have resolved.
- Protein in the urine may also be a warning sign of a serious condition. Typically, three positive urine samples over a period of time without other significant symptoms will often be followed up with additional tests, including 24-hour urine. Persistent and an increased amount of protein in the urine may indicate kidney damage or disease. With kidney disease, the amount of protein present is generally associated with the severity of the damage.
