Protein electrophoresis - urine
Alternative namesUrine protein electrophoresis; UPEP
DefinitionThis is a test that roughly quantitates the various protein fractions in urine. (See also immunoelectrophoresis - urine ; immunofixation - urine .)
How the test is performed
Child or adult:
Electrophoresis is a laboratory technique. The urine is placed on specially treated paper and exposed to an electric current. The various proteins migrate (move on the paper) to form bands that indicate the relative proportion of each protein fraction.
How to prepare for the testCollection of the first morning urine, which is the most concentrated, may be advised. The health care provider may advise you to discontinue drugs that could interfere with the test.
How the test will feelThis test involves only normal urination, and there is no discomfort.
Why the test is performed
Protein is not normally found in large quantities in the urine. However, the presence of protein in the urine can indicate a multitude of disorders.
Urine protein is roughly divided into urine albumin and globulins. Urine protein electrophoresis may be recommended to help determine the cause of protein in the urine or as a screening test to semi-quantitatively measure the various proteins in urine.
No significant amount of globulin protein in the urine .
Urine albumin is less than 50 mg/dL.
What abnormal results mean
What the risks areThere are no risks associated with this test.
Special considerationsDrugs that can affect the measurement of serum proteins include chlorpromazine, corticosteroids, isoniazid, neomycin, phenacemide, salicylates, sulfonamides, and tolbutamide. Never discontinue any medication without consulting with your health care provider.
