Protein - urine
Alternative namesUrine protein; Albumin - urine; Urine albumin; Proteinuria; Albuminuria
DefinitionA urine albumin test measures the amount of protein in urine.
How the test is performed
Urine protein is tested by one of these methods:
The health care provider will instruct you, if necessary, to discontinue drugs that may interfere with the test. The procedure for collecting urine over 24 hours is as follows:
In infants, thoroughly wash the area around the urethra. Open a urine collection bag (a plastic bag with an adhesive paper on one end), and place it on the infant. For males, the entire penis can be placed in the bag and the adhesive attached to the skin. For females, the bag is placed over the labia. Diaper as usual over the secured bag. This procedure may take a couple of attempts -- lively infants can displace the bag, causing the specimen to be absorbed by the diaper. The infant should be checked frequently and the bag changed after the infant has urinated into the bag. The urine is drained into the container for transport to the laboratory.
How to prepare for the testThe health care provider may advise the person to discontinue drugs that can interfere with the test. (See Special Considerations.)
In infants and children:
The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For general information regarding how you can prepare your child, see the following topics:
How the test will feelThe test only involves normal urination, and there is no discomfort.
Why the test is performed
This test is most often performed when kidney disease is suspected. It may be used as a screening test.
Some proteins will appear in the urine if the levels of protein in blood become high, even when the kidney is functioning properly.
If the kidney is diseased, protein will appear in the urine -- even if the blood levels are normal.
Note: mg/dl = milligrams per deciliter
