Complete Blood Count (CBC) Test

A complete blood count (CBC) is a common blood test that measures the different cells in your blood, including red blood cells, white blood cells, and platelets, to help evaluate your overall health and detect a wide range of conditions, such as anemia, infection, and clotting problems.

The anaerobic peritoneal fluid culture is a laboratory test that looks for anaerobic bacteria in fluid taken from the peritoneal cavity (the space inside your abdomen). Anaerobic bacteria are microorganisms that can grow without oxygen. This test helps doctors identify the specific bacteria causing an abdominal infection so they can prescribe the most effective treatment.

How is the sample collected? A small blood sample is usually drawn from a vein in your arm by a trained healthcare professional, a process that typically takes only a few minutes and causes little more than a brief pinch; the sample is then sent to a laboratory for analysis.

A healthcare provider collects peritoneal fluid using a procedure called paracentesis (abdominal tap). A thin needle is inserted through the skin into the abdominal cavity to withdraw fluid. The sample is then placed in special containers that don't contain oxygen and sent to the laboratory for culture and analysis.

Your doctor may order this test as part of a routine checkup, to investigate symptoms such as fatigue, weakness, fever, or unusual bruising, to diagnose a condition like anemia or infection, or to monitor how a known condition or treatment, such as chemotherapy, is affecting your blood cells.

Your doctor may order this test if you have symptoms of a serious abdominal infection such as peritonitis (inflammation of the abdominal lining), abdominal pain, fever, or swelling. It is commonly used when there is suspicion of an infection following surgery, abdominal trauma, or a ruptured organ.
