Interpretation of the results of the albumin serum test is based on the normal range for albumin levels, which varies slightly depending on the laboratory that performs the test. In general, normal albumin levels range from 3.4 to 5.4 grams per deciliter (g/dL) in adults.
Low levels of albumin may indicate liver or kidney disease, malnutrition, or a protein-losing condition. Symptoms of low albumin levels can include swelling in the legs, feet, or abdomen, fatigue, and weakness. Treatment for low albumin levels depends on the underlying cause, but may involve dietary changes, medication, or intravenous administration of albumin.
High levels of albumin are less common, but may indicate dehydration, a rare genetic disorder called hereditary angioneurotic edema, or other underlying medical conditions. Treatment for high albumin levels depends on the underlying cause, but may involve fluid replacement therapy or treatment of an underlying medical condition.
