Description:
Protein Electrophoresis, Urine (24-Hour)Test (Labcorp)
The UPEP/Protein Electrophoresis urine test detects and measures certain proteins in a 24-hour urine sample. This test uses an electrical field to separate proteins into groups based on size, shape, and electrical charge. Results for this test will provide measurements for the five major protein fractions, Albumin, Alpha-1-Globulin, Alpha-2-Globulin, Beta Globulin, and Gamma Globulin, as well as Total Protein, Albumin, and M-spike if present. Normally, there will be little or no protein in the urine. The presence of proteins can indicate a number of conditions including urinary tract infection, inflammation, decreased kidney function, diabetic kidney disease, and a type of blood cancer called multiple myeloma. Testing a 24-hour urine sample can provide more information that a single random sample by measuring the average protein levels over a whole day rather than at one particular time.
A UPEP test is sometimes ordered if someone shows irregular protein levels in the urine from a Urinalysis test. A Serum Protein Electrophoresis is often ordered at the same time. A Random Urine Test is also available.
Turnaround for this test is typically 3-6 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Requirements:
For 24-hour urine specimen: Obtain a specimen container and instructions from the draw site. Void at 8 AM and discard the specimen. Then collect all urine including the final void at the end of the 24-hour collection period (ie, 8 AM the next morning) in the specimen container. Screw the lid on securely and return the container promptly to the draw site.
If this test is being ordered along with any other blood and/or urine medical testing, it is recommended you have the specimen(s) for your other tests collected at the same time you bring the 24-hour urine specimen to the draw site.
