24-Hour Urine Protein What to

A 24-hour urine protein test measures the amount of protein in your urine over a 24-hour period. It is used to diagnose and monitor kidney disease and other conditions that can cause protein to leak into your urine.

Why is a 24-hour urine protein test done?

A 24-hour urine protein test may be done to:

- Diagnose kidney disease. A high level of protein in the urine can be a sign of kidney damage.

- Monitor kidney disease. If you have kidney disease, a 24-hour urine protein test can be used to track your condition and see how well your treatment is working.

- Diagnose other conditions. A high level of protein in the urine can also be caused by other conditions, such as diabetes, lupus, and sickle cell anemia.

How do I prepare for a 24-hour urine protein test?

Your doctor will give you specific instructions on how to prepare for the test. Generally, you will need to:

- Collect all of your urine for 24 hours, starting and ending at the same time each day.

- Avoid strenuous exercise during the 24-hour period.

- Avoid taking any medications that can affect your urine protein levels, such as diuretics.

- Drink plenty of fluids to ensure you produce enough urine.

How is a 24-hour urine protein test performed?

To collect your urine for the test, you will need to use a special container that your doctor will provide. You will need to empty your bladder completely into the container every time you urinate. At the end of the 24-hour period, you will need to return the container to your doctor's office.

Your doctor will send your urine sample to a laboratory for testing. The laboratory will measure the amount of protein in your urine and compare it to a normal reference range.

What are the risks of a 24-hour urine protein test?

A 24-hour urine protein test is a safe and simple procedure. There are no known risks associated with the test.

What do the results of a 24-hour urine protein test mean?

The results of a 24-hour urine protein test can be interpreted as follows:

- Normal: Less than 150 mg of protein in 24 hours

- Mild proteinuria: 150 to 500 mg of protein in 24 hours

- Moderate proteinuria: 500 to 2,000 mg of protein in 24 hours

- Severe proteinuria: More than 2,000 mg of protein in 24 hours

A high level of protein in the urine can be a sign of kidney disease. However, it is important to note that a single high protein level does not necessarily mean that you have kidney disease. Your doctor will order additional tests to confirm a diagnosis of kidney disease.

If you have any questions about the results of your 24-hour urine protein test, talk to your doctor.
