What Is Albumin?
Albumin is the most abundant protein in human blood plasma. It is produced by the liver and plays an essential role in maintaining fluid balance, transporting hormones, vitamins, medications, and other substances throughout the body, and supporting overall health.
Healthcare providers often measure albumin levels as part of routine blood work to evaluate nutritional status, liver function, kidney function, and certain chronic medical conditions.
