Albumin
- Sample Type
- Standard
- Fasting
- No
- Unit
- g/dL
Albumin is the most abundant protein in human blood plasma and is synthesized exclusively by the liver. In the context of a Proteins & A/G Ratio panel, it serves as a primary indicator of nutritional status and hepatic synthetic function. It maintains oncotic pressure (keeping fluid in the blood vessels) and acts as a transport protein for hormones, vitamins, and drugs. It is considered a 'negative acute-phase reactant,' meaning levels drop during periods of acute inflammation or injury.

Why Context Matters
Albumin levels are significantly affected by hydration status; dehydration can cause a false elevation (hemoconcentration). Conversely, overhydration or pregnancy can dilute albumin levels. Chronic inflammation can suppress albumin synthesis even if liver function and nutrition are adequate.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
