ASCITES FLUID  removed by punction is cloudy yellowish.

Ascites fluid analysis: cytology no malignant cell, 75%  lymphocyte, protid 30,6g/L, sugar 5,3 g/dL, amylase not elevated.

CEA=   650 UI/L;   CA-125 =550 UI/L

ADA = NEGATIVE , PCR TB = NEGATIVE.

Summary =   With blood test and ascites fluid test results , we try to find out cancer by gastroscopy, colonoscopy.
MDCT TOTAL BODY and  MRI abdomen also no detected cancer.
