Reference Range	Albumin, Pericardial Fluid, Peritoneal Fluid & Pleural Fluid – The serous cavities surrounding the abdomen, heart and lungs will accumulate fluids, called effusions, when their production or resorption is not in balance. The serum-effusion albumin gradient is used to classify whether an effusion is a transudate or an exudate. * A gradient value of >1.2 g/dL is seen in transudates * A gradient value of <= 1.2 g/dL is seen in exudates Albumin, Synovial Fluid – Chemical analysis of synovial fluid offers supportive information to routine tests for inflammatory disorders. * Synovial albumin approximates 55-70 % of serum albumin g/dL level.
