Albumin
The main liver-synthesized serum protein - low levels signal liver dysfunction, malnutrition, or chronic disease.

What Albumin Measures
Albumin is the most abundant serum protein, synthesized exclusively by the liver. It is a cleaner long-term marker of liver synthetic function than ALT (half-life ~20 days vs minutes). Low values (<3.5) suggest chronic liver disease, malnutrition, nephrotic syndrome, or sustained inflammation.
Albumin is the primary carrier for hydrophobic molecules including calcium and many drugs - corrected calcium uses albumin.
What Affects This Biomarker
Albumin is influenced by: liver synthetic capacity (chronic disease lowers), protein intake, inflammation (negative acute phase reactant - falls during illness), nephrotic syndrome (urinary loss), and volume status (hemodilution in overload).
In the Context of Peptide Protocols
Reviewed as part of standard CMP. Persistent values below 4.0 warrant follow-up - could be diet, inflammation, or early liver synthetic dysfunction. Longevity cohorts show higher albumin associated with lower all-cause mortality.
