In our study, among the 39 patients who had hypoalbuminemia, four (6.67%) patients had preoperative serum albumin levels less than 2 g/dL, 22 (36.67%) patients had preoperative serum albumin levels of 2-3 g/dL, and 13 (21.67%) patients had serum albumin level of 3-3.4 g/dL. This evidence concerns the gene ALB and Hypoalbuminemia.
