Ascites is the accumulation of a fluid in the abdominal cavity also known as peritoneal space. This fluid is called ascitic fluid. The Culture and Sensitivity Ascitic Fluid test diagnoses the cause of the formation of this fluid. There are two main reasons for this fluid build-up: transudate and exudate. This examination helps in distinguishing between these reasons. The ascitic fluid is of translucent or yellow colour usually. The difference in the colour indicates the presence of health conditions and the results are analysed in that manner. Serious diseases such as tuberculosis, pancreatitis, and others are revealed through this test.
