Albumin helps maintain the oncotic pressure that keeps fluid inside blood vessels and transports many substances, including hormones, medications, and minerals. Low albumin can indicate liver disease, malnutrition, kidney protein loss, chronic inflammation, or significant illness, while elevated values are typically related to dehydration.
This test is part of comprehensive metabolic panels and is also ordered to evaluate edema, ascites, or unexplained weight loss; assess severity of liver or kidney disease; monitor nutritional status; and interpret protein-bound drug or hormone levels. Sample type is serum.
