Urine protein electrophoresis test
About Urine Protein Electrophoresis Test
Urine protein electrophoresis is a laboratory technique used to quantify and identify the proteins present in urine. It belongs to the family of protein electrophoresis (PEP) tests, which separate and measure the proteins in a sample by using electric fields to force them through a porous gel-like medium. This technique is used to detect different types of disease.
Preparation for the Test
An overnight fast is typically not required before the urine protein electrophoresis test, however the patient may be asked to abstain from drug use for a few days prior. Although special preparations are generally not needed, some medical conditions may require additional steps for safety and accuracy. Consult a doctor prior to the test to find out if any special preparation is needed.
Procedure for the Test
The procedure for the urine protein electrophoresis test involves first having a urine sample collected by the laboratory or doctor. This urine sample is then placed on a porous gel-like substance and an electric field is applied across it. As the electric field is applied, the proteins in the sample start to move and separate into distinct bands based on their size and charge. These bands can then be measured and identified.
Types of Protein Electrophoresis Tests
- Basic urine protein electrophoresis (BUPE) test
- Advanced urine protein electrophoresis (AUPE) test
- Protein gel filtration test
- Antibody testing
Risks Associated with Urine Protein Electrophoresis
Urine protein electrophoresis is a safe and relatively painless procedure. The only potential risk involved is a minor discomfort during the collection of the urine sample. In rare cases, further testing may be recommended by a doctor if any abnormal results are found.
When to Have the Test
Urine protein electrophoresis tests are usually recommended when there is suspicion of certain medical conditions such as diabetes, kidney disease, or autoimmune diseases. It is also used as routine screening for certain disorders in newborns and pregnant women. Your doctor will be able to give you more information on when to have the test.
Why Have the Test?
Urine protein electrophoresis is used to identify, quantify, and analyze the proteins present in a urine sample. By understanding the proteins present in a urine sample, doctors are able to diagnose various medical conditions and provide treatment accordingly. It is also a useful tool in monitoring the effectiveness of existing treatments.
