Albumin: what your result means.

Updated 07 August 2026 · HodieLabs Clinical Governance Lead · The HodieLabs Evidence-Based Clinical Library

The most abundant blood protein; reflects liver function and nutritional status. Albumin is measured by blood test as part of the Organ panel in the HodieLabs Health Blueprint.

Why Albumin matters

Albumin is a negative acute phase reactant. It drops during inflammation, infection, and surgery. Low albumin in the absence of inflammation suggests liver synthetic dysfunction or malnutrition.

Associated risks when out of range: Frailty risk proxy (low), Inflammation/nutrition issues (low), Liver/kidney disease (contextual).

What the clinical evidence shows

The evidence base behind how the HodieLabs Evidence-Based Clinical Library interprets Albumin, from randomised trials, prospective cohorts and genetic (Mendelian randomisation) studies. Full citations in the reference list below.

  • EPESE cohort (Corti et al. JAMA 1994): low serum albumin independently predicted mortality in older adults even after adjusting for illness, a robust global signal of physiological reserve, nutrition and inflammation.

Evidence-based reference ranges

The HodieLabs Evidence-Based Clinical Library interprets Albumin against published clinical authority standards, never arbitrary "optimal" ranges. Measured in g/L:

BandRange (g/L)
Optimal33–46 g/L
Low<33 g/L
High>46 g/L
Reference standard: Aligned with largest Australian pathology laboratory reference interval; albumin 33–46 g/L. Consistent with RCPA guidance (35–50 g/L narrowed to match BCG-method assay ranges used by major Australian labs).

Clinical interpretation

  • Albumin is a negative acute phase reactant. It drops during inflammation, infection, and surgery.
  • Low albumin in the absence of inflammation suggests liver synthetic dysfunction or malnutrition.
  • Albumin <35 g/L is an independent predictor of mortality in hospitalised patients.

What improves it: the evidence-based levers

  • Improve protein intake if appropriate
  • Address inflammation drivers
  • Clinical review if low

Recommended testing frequency: Annual, as part of a comprehensive panel. Single markers are always interpreted in context.

How Albumin testing works at HodieLabs

Albumin is measured in every Health Blueprint at our Melbourne Preventative Health & Longevity Clinic, interpreted by a doctor against the guideline-cited ranges above and tracked over time through your HodieLabs membership.

Frequently asked questions

The most abundant blood protein; reflects liver function and nutritional status.

The HodieLabs Evidence-Based Clinical Library optimal range is 33–46 g/L, based on Aligned with largest Australian pathology laboratory reference interval; albumin 33–46 g/L. Consistent with RCPA guidance (35–50 g/L narrowed to match BCG-method assay ranges used by major Australian labs).

Annual testing is recommended for most adults as part of a comprehensive preventative panel; more often if a result is being actively managed.

Evidence-supported levers include: improve protein intake if appropriate, address inflammation drivers, clinical review if low. Interpretation and an action plan should always involve your doctor.

Albumin is measured in the HodieLabs Health Blueprint at our Melbourne Preventative Health and Longevity Clinic at 85 Spring Street, with doctor-led interpretation against evidence-based reference ranges.
