Guided Chest Tube Output Protein Excretion (24-hour urine collection)
This test measures the total amount of protein found in your urine over 24 hours after a chest tube procedure. It helps assess whether your body is losing too much protein through your urine, which can indicate kidney function or fluid balance issues.

Why This Test Is Done
Your healthcare provider may order this test if you’ve had a chest tube inserted to drain fluid or air from your chest cavity. After the tube is removed, they may check for protein in your urine to monitor for signs of kidney strain or fluid retention. This can help ensure proper healing and prevent complications like swelling in your legs or arms.
What to Expect Before the Test
You’ll need to collect all urine for a full 24-hour period after your chest tube is removed. Typically, you’ll start the collection right after the tube is taken out and continue until you’ve collected urine for the next full day. Your healthcare team will provide instructions on how to properly collect and store the urine samples to ensure accuracy.
What the Test Results Mean
Higher-than-normal protein levels in urine after a chest tube procedure might suggest your kidneys are working harder than usual or that fluid is improperly redistributing in your body. Your provider will discuss these results with you and may recommend further tests or adjustments to your care plan if needed.
Common Causes of Abnormal Results
Protein in urine after chest tube removal can occur due to normal healing processes, but elevated levels may also be linked to conditions like kidney strain, fluid overload, or improper fluid balance. Your provider will consider your overall health and symptoms when interpreting these results.
