g/dL

Albumin is the most abundant plasma protein, synthesized exclusively by the liver. In a Liver Function Test, it serves as a biomarker for the liver's synthetic capacity and the patient's nutritional status. It is critical for maintaining colloid osmotic pressure, preventing fluid from leaking out of blood vessels into tissues (edema), and acts as a transport protein for hormones, vitamins, and drugs.

Why Context Matters

Albumin is a 'negative acute-phase reactant,' meaning levels drop during any acute inflammatory state, infection, or after surgery, regardless of liver health. Hydration status significantly affects results; overhydration lowers it, while dehydration raises it.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
