Significance of Elevated Serum Albumin

Understanding Serum Albumin

• Normal serum albumin range is approximately 3.5-5.0 g/dL (laboratory-specific ranges may vary) 3

Causes of Elevated Serum Albumin

• Elevated serum albumin levels are uncommon and typically reflect dehydration (most common cause) - resulting in hemoconcentration of plasma proteins 1, 2
• Resolution of inflammatory conditions - as albumin is a negative acute-phase reactant that increases following recovery from inflammation 1
• Increased protein or energy intake - albumin levels may rise modestly with increased nutritional intake 1

Clinical Significance and Evaluation

• Assess for recent dietary changes, particularly high protein intake 1

Management Approach

• If albumin remains elevated despite adequate hydration, consider further evaluation for other causes 1

Important Considerations

• Serum albumin should be interpreted in the context of the patient's overall clinical status, including hydration status and comorbid conditions 3
• Albumin measurement methods may vary between laboratories, so reference ranges should be laboratory-specific 3
• Serial monitoring of serum albumin is more informative than a single measurement 4

Common Pitfalls

• Failing to recognize that albumin levels are affected by multiple factors beyond nutrition, including inflammation and hydration status 1, 2
• Not considering laboratory method variations when interpreting albumin results 3
