Spontaneous Bacterial Peritonitis

To diagnose SBP, your doctor will typically perform a procedure called a paracentesis. This involves carefully removing a sample of the ascites fluid using a needle, which is then sent to the lab. The lab analyzes the fluid for signs of infection, primarily by counting certain white blood cells (neutrophils) and attempting to grow any bacteria present. These tests are vital for confirming SBP, guiding the most effective antibiotic treatment, and monitoring your response, which helps to prevent severe complications and improve your overall health.
