Several methods for the examination of ascites

        Laboratory examination:

        Laboratory tests are often used as an important means to discover the cause of the disease. Liver function damage and low serum albumin may indicate liver cirrhosis, a large number of proteinuria, blood urea nitrogen and creatinine elevation indicate that renal function is impaired, immunological examination of liver and kidney disease diagnosis also has important significance.

        The nature of ascites can be determined by the examination of abdominal puncture fluid.

        1 general checks

        (1): the appearance of transudate was pale yellow, thin and transparent, exudate can come in different colors or opacity. Different causes of ascites can be different in appearance, such as pyogenic infection of yellow pus or purulent; Pseudomonas aeruginosa infection of ascites was green yellow; jaundice; hemorrhagic ascites in acute tuberculous peritonitis, malignant tumor; chylous ascites was white self coagulation, because non inflammatory products so is still a transudate.

        (2) relative density: relative density in transudate exudate below 1.018; relative density of more than 1.018.

        (3): clot formation exudate containing fibrinogen and tissue, cell damage and release coagulin, so it is easy to clot or floc.

        2 biochemical examination

        (1) mucin (qualitative test of mucin) qualitative test: transudate exudate was negative. Quantitative transudate exudate is greater than 0.25g/L less than 0.25g/L.

        (2) the increase of amylase in pancreatic ascites.

        (3) bacteriology and histologic examinations: ascites after centrifugation smear staining can be found in bacteria, acid fast stain can be found in Mycobacterium tuberculosis, necessary for bacterial culture or animal inoculation. The tumor cells can be found in ascites, which is very necessary for the diagnosis of abdominal tumor. The sensitivity and specificity of the tumor can reach 90%.

        Other auxiliary examination:

        1 ultrasound and CT examination can not only display a small amount of ascites, but also shows the liver capsule size, liver smoothness, intrahepatic lesions, heart size, heart structure, inflow and outflow tract, blood flow, renal size, morphology, structure etc..

        2 ECG examination can be found in the heart of the changes in the heart, blood supply.
