Bicarbonate: what your result means.

A buffer that maintains blood pH; reflects acid-base balance. Bicarbonate is measured by blood test as part of the Organ panel in the HodieLabs Health Blueprint.

Why Bicarbonate matters

Interpret in clinical context and with medications (e.g. diuretics). 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: Electrolyte imbalance, Cardiac/neuromuscular effects when abnormal (contextual).

Evidence basis

The HodieLabs Evidence-Based Clinical Library classifies Bicarbonate 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; serum bicarbonate 22–30 mmol/L normal acid-base balance. 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 Bicarbonate against published clinical authority standards, never arbitrary "optimal" ranges. Measured in mmol/L:

Clinical interpretation

• Interpret in clinical context and with medications (e.g. diuretics).
• 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

• Hydration/electrolyte management
• Clinical review if abnormal

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

How Bicarbonate testing works at HodieLabs

Bicarbonate 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.
