Normal albumin levels are within which range?

• A. 2.9-3.9 g/dL
• B. 4.0-4.8 g/dL
• C. 3.4-5.4 g/dL
• D. 6.0-7.0 g/dL

Answer: (C)

Normal albumin levels in the bloodstream are about 3.4 to 5.4 g/dL. This range is a standard reference used by clinicians because albumin, produced by the liver, helps maintain plasma oncotic pressure and carries various substances. Within this span, most adults have adequate liver function and no significant losses or inflammatory changes. Values below 3.4 g/dL indicate hypoalbuminemia, seen with malnutrition, liver disease, kidney loss, or systemic inflammation. Values around 6.0 g/dL or higher are not typical in healthy individuals and suggest dehydration or lab variation rather than a true elevation. The 3.4–5.4 g/dL range best matches the common reference interval.
