Although majority of the cases of ascites have cirrhosis, there are 15% patients where there is a non-hepatic cause of fluid retention like malignancy, congestive heart failure and tuberculous peritonitis. Ascites is the most common complication of cirrhosis that leads to hospital admission. Objective:To compare the diagnostic Accuracy of Serum Ascitic Albumin Gradient (SAAG) and Ascitic Fluid Total Proteins in patients with ascites by taking Ultrasound abdomen &amp; Pelvis as gold standard. There are international studies on the accuracy of SAAG in determining cause of ascites but not much local data. Additionally, SAAG is not widely used in our setup. The results of this study will add to the existing knowledge and will help in the diagnosis and better management of these patients. Material &amp; Methods: A cross sectional validation study was conducted in the department of General Medicine, DHQTH, Dera Ismail Khan from 29th April to 29th Oct, 2019. Diagnostic Ascitic fluid was aspirated from the peritoneal cavity and ascitic fluid was sent to hospital laboratory for total protein and albumin. Blood was taken at the same time and was send to the hospital laboratory for the serum albumin. SAAG was calculated by subtracting ascitic albumin value from the serum albumin value. Both, Ascitic fluid total protein and SAAG values was documented in the proforma. Ultrasound Abdomen &amp; Pelvis was done on each patient with special instruction for radiologist to comment upon Portal Vein diameter and any changes in its diameter with respiration. Results: As per comparison Of SAAG with ultrasound in detecting ascites, sensitivity was 36.26%, specificity was 75%, PPV was 84.62%, NPV was 23.68% and accuracy was 44.35%. P Value was 0.299. As per comparison of AFTP with ultrasound in detecting ascites, sensitivity was 33.33%, specificity was 59.34%, PPV was 17.78%, NPV was 77.14% and accuracy was 53.91%. P value was 0.513. Conclusion:SAAG exhibits that patients with ascites fluid possess the basis of portal hypertension. Thus we have come to this conclusion that SAAG can effectively enhance the diagnostic value of ascites fluid tests and therefore its classification can be considered to be a novel standard in the analysis of ascites fluid. Keywords: Diagnostic Accuracy, Ascites Volume, Ascitic Albumin Gradient (SAAG), Ascitic Fluid Total Proteins (AFTP)
