How the Test is Performed A clean-catch urine sample is needed. The clean-catch method is used to prevent germs from the penis or vagina from getting into a urine sample. To collect your urine, the health care provider may give you a special clean-catch kit that contains a cleansing solution and sterile wipes. Follow instructions exactly so that the results are accurate.Clean-catch urine sampleA clean catch is a method of collecting a urine sample to be tested.

There are many methods used to detect Bence-Jones proteins. One method, called immunoelectrophoresis, is the most accurate.ImmunoelectrophoresisThe urine protein electrophoresis (UPEP) test is used to estimate how much of certain proteins are in the urine.ImageRead Article Now Book Mark Article How the Test will Feel The test involves only normal urination, and there is no discomfort. Why the Test is Performed Bence-Jones proteins are a part of regular antibodies called light chains. These proteins are not normally in urine. Sometimes, when your body makes too many antibodies, the level of light chains also rises. Bence-Jones proteins are small enough to be filtered out by the kidneys. The proteins then spill into the urine. AntibodiesAn antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include micr...ImageRead Article Now Book Mark Article Your provider may order this test:To diagnose conditions that lead to protein in the urine If you have a lot of protein in your urine If you have signs of a blood cancer called multiple myelomaMultiple myelomaMultiple myeloma is a blood cancer that starts in the plasma cells in the bone marrow.
