Why This Test Is Done

Your healthcare provider may order this test if you have a drainage catheter in place to monitor for issues like infection (such as abscess or cellulitis), leakage, or changes in fluid composition. It helps ensure the catheter is functioning properly and that no complications are developing.

What to Expect Before the Test

No special preparation is typically needed. You may be asked to empty your bladder before the test if urine is involved in the fluid analysis. If stool or other bodily fluids are assessed, standard hygiene practices (such as washing hands) are recommended.

What Happens During the Test

The fluid is collected from the catheter and sent to the lab. The lab will analyze the fluid for specific characteristics, such as presence of bacteria, white blood cells, or other markers. The test may involve qualitative (yes/no) or quantitative (measured) analysis depending on the clinical question.

What the Results Mean

Results may indicate normal drainage, signs of infection (e.g., high white blood cell count, pus), inflammation, or other abnormalities. Your healthcare provider will interpret the results in the context of your medical history and symptoms.
