What is the normal serum albumin level?

• A. 2.5-4.0
• B. 3.5-5.0
• C. 4.5-6.0
• D. 7.0-8.0

Answer: (B)

Albumin is a protein produced by the liver that helps keep fluid in the bloodstream (oncotic pressure) and carries various substances in the blood. The normal serum albumin level is about 3.5 to 5.0 g/dL. Among the given ranges, this one matches the expected normal value. Values below 3.5 g/dL suggest hypoalbuminemia, which can occur with malnutrition, liver disease, or loss of protein in the kidneys. Values above 5.0 g/dL are not typical and may indicate dehydration or lab variation; the ranges 2.5-4.0, 4.5-6.0, and 7.0-8.0 lie outside the normal interval.
