What is the normal range for Albumin?

• A. 3.4-5.4
• B. 3.0-4.0
• C. 4.0-5.0
• D. 3.8-5.0

Answer: (A)

Albumin is the main plasma protein that helps keep fluid in the blood vessels (oncotic pressure) and also carries various substances through the blood. The normal serum albumin range most commonly cited is about 3.4 to 5.4 g/dL, though some labs report a similar range with slight variations. This interval reflects adequate liver synthesis and nutritional status. Values below this range indicate hypoalbuminemia, which can occur with malnutrition, liver disease, nephrotic syndrome, or inflammatory/protein-losing states. High values are uncommon and usually point to dehydration or concentrated samples, but the exact interpretation should consider the clinical context and lab method.
