Pleural or ascitic fluid should be sent for analysis. An elevated amylase level, usually > 1,000 IU/L, with protein levels over 3.0 g/dL is diagnostic. Complete blood count is necessary to check for any ongoing infection or hemorrhage. Complete metabolic panel including inflammatory markers, serum electrolytes, liver function tests, calcium, albumin, amylase and lipase should be sent to laboratory for evaluation. Furthermore, pancreatic<unk>  leak presenting as ascites or pleural effusion should be analyzed for fluid protein, albumin, lactate dehydrogenase, glucose, gram cultures and total cell count.
