Definition

Albumin is a protein produced by the liver. It has two critical roles: 1. It keeps the fluid part of your blood from leaking out of your blood vessels 2. It carries hormones, vitamins and enzymes through the body

Purpose

Assessment of general health, nutritional status and liver and kidney function. Ordered at routine check-ups, as part of liver function tests or a comprehensive metabolic panel. Investigated for symptoms such as jaundice, abdominal swelling, fatigue or changes in urination.

Results

  • Low albumin, liver disease (cirrhosis, hepatitis), kidney disease, malnutrition, infection, digestive disorders, severe burns or thyroid disease
  • High albumin, usually dehydration (e.g. after severe diarrhea)

Normal Values

Laboratory specific.

Risks and Limitations

Cannot make a diagnosis on its own. Certain medications (steroids, insulin, birth control pills) and pregnancy affect the results; fasting or recent poor nutrition can lower albumin.
