Albumin Unit Converter
Albumin is the most abundant protein in human blood plasma, constituting about 55-60% of total serum protein. Synthesized exclusively by the liver, it serves two critical physiological functions: maintaining colloid osmotic (oncotic) pressure to prevent plasma leakage into tissues, and acting as a carrier molecule for hormones, fatty acids, unconjugated bilirubin, calcium, and drugs.
Measurement of serum albumin is a staple of the Comprehensive Metabolic Panel (CMP) and Liver Function Tests (LFTs). Low levels (hypoalbuminemia) may indicate liver cirrhosis, nephrotic syndrome (kidney loss), malnutrition, or acute inflammation (as a negative acute-phase reactant). High levels are almost exclusively a sign of dehydration. This converter facilitates accurate switching between the international standard (g/L), the molar unit (µmol/L), and the conventional g/dL.

Clinical Context
The reference range for serum albumin in adults is typically 35 – 50 g/L (3.5 – 5.0 g/dL). Because albumin has a long half-life (~20 days), it is a good marker for chronic nutritional status but poor for acute changes.
Albumin levels are essential for interpreting total calcium levels; roughly 50% of serum calcium is bound to albumin. In hypoalbuminemia, total calcium may appear falsely low (“pseudohypocalcemia”). The conversion factor for molar mass is based on HSA MW ~66,437 Da: 1 g/dL ≈ 150.5 µmol/L.
