If the albumin is lower than 20, the main way to replenish the albumin is through intravenous infusion of human blood albumin, and at the same time, it can be supplemented with dietary supplements and oral protein powder. If the albumin is mildly low, it can be elevated through dietary modification, eating foods rich in high-quality protein, such as cow’s milk, goat’s milk, as well as lean meat, fish, shrimp, shells, seafood and other foods. If the albumin drops further below 20 grams per liter, human albumin can be given intravenously. Human albumin is a plasma product. During the infusion, watch for infusion reactions and allergic reactions. If an allergic reaction occurs, stop immediately. In the event that albumin is below 20, it is important to go to a specialized hospital for consultation and treatment after clarifying the cause of the disease, and not to simply supplement albumin to prevent recurrent episodes of low albumin.
