Albumin is the main plasma protein of blood that maintains oncotic pressure and transports bilirubin, fatty acids, medications, hormones, and other substances that are insoluble in water. Albumin is increased in conditions such as dehydration, diarrhea, and metastatic carcinoma; decreased in conditions such as acute infection, ascites, and alcoholism. Presence of detectable albumin, or protein, in the urine is indicative of abnormal renal function.
