A urine protein test is used to detect the presence of protein in a person's urine.
A test for protein in urine is done when a person is suspected of having: kidney problems with high blood pressure any kidney diseasediabetesmultiple myeloma, a tumor in the blood and bone marrow
Pregnant women are routinely tested for protein in the urine during prenatal visits to the healthcare provider. Protein in the urine during pregnancy may indicate preeclampsia, a serious condition that can cause high blood pressure and seizures in the mother. For insurance or other physicals like when starting a new job
There are 4 ways to check for urine protein: a urinalysis by a stick put into the urine sample, a random urine specimen that looks for minute amounts of protein (called "micro"albumin testing), a random urine specimen that looks for large amount of protein in the urine ("macro"albumin), and by 24 hour urine collections.
For the urinalysis or spot testing, a person is asked to supply a single, small urine sample.
First, the area around the urethra should be washed. Then, the person should: start urinating in the toiletcatch a sample of urine in the containerfinish urinating in the toilet
The container should be covered and delivered to the health care provider for testing. The sample is usually the first urine of the day. Sometimes a 24-hour urine collection is needed for more accurate results. In this process, a person collects all the urine he or she voids during an entire 24-hour period.
In general, this schedule is followed: Day 1: The patient urinates upon arising as usual and discards that urine For example, at 7 a.m. on Monday). Then, the person collects all urine produced for the next 24 hours in a special container.Day 2: First thing the follwing morning (for example 7 a.m. Tuesday morning), the person collects the morning urine again in the container. Then the person covers the container and refrigerates it until it can be taken to the healthcare provider or assigned laboratory.
Often, urinary protein and several other substances are measured at the same time in a screening test known as urinalysis.
A person should request specific instructions from his or her health care provider.
Normally, there should be no protein detected in the urine. The presence of protein may indicate: kidney disease kidney injury from any cause including high blood pressureearly kidney or blood vessel injury in diabetes ("micro"albumin)preeclampsia of pregnancy
