Abdominal tap - paracentesis; Paracentesis
The abdomen usually contains a small amount of fluid. In certain conditions, fluid can accumulate in the abdomen. The abdominal tap is a procedure in which a needle is inserted through the abdominal wall into the peritoneal cavity to obtain a sample of any fluid that is present. The sample is then sent to the laboratory for analysis.
