Protein 24-Hour Urine Test
Test Code: 003277
Specimen Type: Urine
Protein 24-Hour Urine Test (Labcorp)
This test measures Protein levels in a 24 hour urine sample. Normally, the kidneys filter out protein and return it to the blood so little to no protein should be present in the urine. When protein is present, it may be indicative of kidney damage or other conditions such as infections or high levels of stress.
A Protein 24 Hour Urine Test may be ordered as a follow up to a Complete Urinalysis test which shows the presence of protein. It may also be ordered when a person has symptoms of a Urinary Tract Infection or Kidney Disease. Blood tests such as a Comprehensive Metabolic Panel or Protein Electrophoresis may be done as a follow up to a Urine Protein test.
While a 24 hour urine collection is the preferred method of measuring protein in urine, customers may also order a Protein and Creatinine Urine test as an alternative. This test requires only a single urine collection and has a similar level of accuracy.
Turnaround time for the Protein, Total 24-hour Urine test is typically 1 business day.
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.
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.
