Albumin is a protein synthesized by the liver. It plays a critical role in maintaining oncotic pressure within blood vessels, preventing fluid from leaking out into tissues. As the most abundant protein in human plasma, it also acts as a transport molecule, carrying hormones, fatty acids, bilirubin, and many drugs. Its concentration in the blood provides insight into liver function and nutritional status. Albumin has a relatively long half-life, making it a stable indicator over time.
