Ascitic Fluid Analysis

An ascitic fluid analysis is advised when there is new or unexplained abdominal swelling due to fluid (ascites). It is also urgently recommended for people with ascites who develop fever, abdominal pain or tenderness, confusion, or worsening kidney function, to rule out infection (SBP), and when tuberculosis or cancer is suspected.

An ascitic fluid analysis requires paracentesis, a procedure where fluid is removed from the abdomen with a needle. Fasting is usually not required. Empty your bladder just before the procedure. Inform your doctor about any blood thinners, bleeding disorders, allergies, or pregnancy. A blood sample is usually taken at the same time for comparison.

No, fasting is usually not required for an ascitic fluid analysis. You can eat and drink normally before the paracentesis procedure unless your doctor advises otherwise. Remember to empty your bladder just before the procedure, and inform your doctor about any blood thinners or bleeding disorders.
