Why This Test Is Done
Your healthcare provider may order this test if you have symptoms like swelling in your abdomen, unexplained weight loss, or signs of liver dysfunction. It’s also used to monitor drainage after procedures or in cases where fluid is collecting in the liver area.
What to Expect Before the Test
No special preparation is usually needed, but you may be asked to fast for a few hours before the procedure. The drainage catheter is placed under imaging guidance, and fluid is collected over time for analysis.
What the Test Measures
The test analyzes various substances in the drainage fluid, including proteins, electrolytes, bacteria, and signs of inflammation. These results help determine if there’s an infection, fluid imbalance, or other liver-related issues.
Common Findings and Their Meanings
High protein levels may indicate liver cell damage, while elevated white blood cells suggest infection. Low sodium or potassium could signal fluid shifts or kidney issues. Abnormal pH or glucose levels may point to metabolic problems.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test plays a key role in diagnosing and managing conditions like liver abscesses, infections, or portal hypertension. It helps guide treatment decisions, such as adjusting medications or drainage procedures, to improve liver function and reduce complications.
