Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like swelling in your abdomen, fatigue, or signs of liver disease. It helps check how well your liver is working and whether fluid is leaking into your abdomen.

What to Expect During the Procedure

A small tube (catheter) is placed into your abdomen to drain fluid. You may feel mild discomfort, but it’s usually quick and done under guidance to ensure safety.

What the Test Measures

The drained fluid is analyzed for markers like albumin, protein levels, and other substances that indicate liver function or infection. These results help diagnose or monitor conditions like cirrhosis or infections in the abdomen.

Common Conditions This Test Helps Diagnose

This test can identify liver disease, infections in the abdomen (like peritonitis), or how well your liver is retaining proteins that keep fluid in your bloodstream.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
