Albumin/Globulin ratio: what your result means.

Ratio of albumin to globulin; helps assess liver function and immune balance. Albumin/Globulin ratio is measured by blood test as part of the Organ panel in the HodieLabs Health Blueprint.

Why Albumin/Globulin ratio matters

A/G ratio is derived from albumin and total protein. Globulin = total protein - albumin. Monoclonal gammopathy (MGUS, myeloma) classically presents with a low A/G ratio and an M-spike on SPEP.

Associated risks when out of range: Low A/G ratio suggests elevated globulins (chronic inflammation, infection, or myeloma). High A/G ratio is less clinically significant but may occur in immunodeficiency.

Evidence basis

The HodieLabs Evidence-Based Clinical Library classifies Albumin/Globulin ratio as an strong evidence-tier biomarker. Its reference ranges come from a published authority standard rather than from observational optimisation targets. The standard used here is RCPA Australian pathology reference intervals; albumin:globulin ratio 1.0–2.2 normal, reflects hepatic synthetic function. Where relevant clinical outcomes are noted on this page, they reflect the guideline literature referenced below.

Evidence-based reference ranges

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

Clinical interpretation

• A/G ratio is derived from albumin and total protein. Globulin = total protein - albumin.
• Monoclonal gammopathy (MGUS, myeloma) classically presents with a low A/G ratio and an M-spike on SPEP.
• Chronic liver disease lowers albumin while increasing globulins, driving the ratio down from both directions.

What improves it: the evidence-based levers

• Low A/G: request protein electrophoresis (SPEP) to characterise the globulin elevation
• Investigate for chronic infection, autoimmune disease, or haematological malignancy

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

How Albumin/Globulin ratio testing works at HodieLabs

Albumin/Globulin ratio 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.
