Globulin: what your result means.

A group of immune and transport proteins; reflects immune and liver activity. Globulin is measured by blood test as part of the Organ panel in the HodieLabs Health Blueprint.

Why Globulin matters

Often derived from total protein and albumin. Interpret using the reporting lab’s reference interval and clinical context; trend over time is often more informative than a single value.

Associated risks when out of range: Elevated globulin indicates chronic inflammation, chronic infection, or monoclonal gammopathy. Low globulin may indicate immunodeficiency or protein loss (nephrotic syndrome).

Evidence basis

The HodieLabs Evidence-Based Clinical Library classifies Globulin 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; globulin 20–35 g/L (derived: total protein minus albumin). 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 Globulin against published clinical authority standards, never arbitrary "optimal" ranges. Measured in g/L:

Clinical interpretation

• Often derived from total protein and albumin.
• Interpret using the reporting lab’s reference interval and clinical context; trend over time is often more informative than a single value.

What improves it: the evidence-based levers

• Elevated globulin warrants protein electrophoresis (SPEP) to characterise the elevation
• Low globulin: check immunoglobulin levels (IgG, IgA, IgM) for immunodeficiency

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

How Globulin testing works at HodieLabs

Globulin 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.
