How often it is optimal to administer albumin needs to be determined based on the specific patient’s condition. Generally speaking, one to two times a week is enough for patients with tumor diseases, and it should be emphasized that the time of albumin injection must be adjusted according to the change of the condition. Albumin needs to be used together with other drugs to speed up the treatment when patients have special conditions, for example, patients with cirrhosis and ascites need to use diuretic drugs together with albumin to get a more significant effect. Albumin is the main component of protein in human plasma, synthesized by the human liver. Albumin maintains the stability of plasma osmotic pressure, ensures the stable exchange between intra- and extracellular fluids and tissue fluids in the body, and spontaneously combines with heavy metal ions in the body to play its detoxification role.
