Albumin
Albumin is a protein produced by the liver and is the most abundant protein in human blood plasma. It plays a crucial role in maintaining oncotic pressure (which keeps fluid within blood vessels), transporting hormones, vitamins, and drugs, and binding to various substances in the blood, including bilirubin, fatty acids, and ions. Albumin levels in the blood can provide important information about liver and kidney function, nutritional status, and overall health. Low albumin levels can indicate liver disease, kidney disease, inflammation, or malnutrition, while high albumin levels are rare and usually not clinically significant. Monitoring albumin levels helps diagnose and manage various conditions, ensuring proper fluid balance and transport functions in the body.
