What is the normal Albumin range?

• A. 3.4-5.4
• B. 3.0-4.0
• C. 3.8-5.6
• D. 3.2-4.8

Answer: (A)

Albumin is a key blood protein produced by the liver that helps maintain intravascular fluid balance and carries various substances in the blood. The normal serum albumin range is about 3.4 to 5.4 g/dL, a reference interval widely used by labs. Values within this range suggest adequate liver protein synthesis and nutritional status. When albumin falls below this range, it can indicate issues like malnutrition, liver disease, nephrotic syndrome, or inflammatory states, which may lead to edema due to decreased oncotic pressure. Higher values are uncommon and usually point to dehydration or a concentrated blood sample. The range of 3.4–5.4 g/dL best matches standard reference values, while the other ranges would not accurately identify typical healthy levels.
