What is the reference range for albumin (ALB) in plasma?

Albumin is the major soluble protein in blood plasma, helping to maintain oncotic pressure and transport many substances. The reference range for albumin in healthy adults is roughly 35–50 g/L (about 3.5–5.0 g/dL). This interval is used because values within it indicate normal liver synthesis and nutritional status. If albumin falls below 35 g/L, it suggests hypoalbuminemia from malnutrition, liver disease, kidney loss, or inflammation. Values above 50 g/L are uncommon and usually point to dehydration or a lab artifact. So the range that matches 35–50 g/L is the standard reference interval.
