Is it helpful to administer human serum albumin when albumin levels are low?

Infusing human serum albumin is beneficial when albumin levels are low. The detailed analysis is as follows:

Infusion of human serum albumin can effectively increase the concentration of albumin in plasma. Albumin has many important functions, including maintaining blood volume, regulating osmotic pressure, transporting drugs, modulating immune responses, and scavenging free radicals. Due to its molecular structure and charge characteristics, albumin creates an osmotic gradient that helps maintain fluid balance between plasma and interstitial fluid. It also reduces capillary wall permeability, preventing fluid leakage into surrounding tissues. Additionally, albumin binds drugs and metabolic byproducts, transporting them to target tissues or cells, and participates in immune regulation and promotion of antibody production. Therefore, albumin is essential for the normal functioning of nearly all cells in the body and constitutes an indispensable component.

In summary, whether human serum albumin infusion is necessary should be determined based on the individual patient's clinical condition. Moreover, albumin infusion carries certain risks, such as infections, allergic reactions, and infusion-related adverse effects.
