White blood cells that become macrophages; involved in chronic inflammation. Monocytes (abs) is measured by blood test as part of the Inflammation panel in the HodieLabs Health Blueprint.
Part of CBC differential. 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 monocytes indicate chronic infection (TB, endocarditis), autoimmune disease, or malignancy. Monocyte count >1.0 × 10⁹/L sustained over months warrants investigation.
The HodieLabs Evidence-Based Clinical Library classifies Monocytes (abs) 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 Aligned with largest Australian pathology laboratory reference interval; monocytes 0.0–1.0 x10^9/L. Where relevant clinical outcomes are noted on this page, they reflect the guideline literature referenced below.
The HodieLabs Evidence-Based Clinical Library interprets Monocytes (abs) against published clinical authority standards, never arbitrary "optimal" ranges. Measured in x10^9/L:
Recommended testing frequency: Annual, as part of a comprehensive panel. Single markers are always interpreted in context.
Monocytes (abs) 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.

White blood cells that become macrophages; involved in chronic inflammation.
The HodieLabs Evidence-Based Clinical Library optimal range is 0.0–1.0 x10^9/L, based on Aligned with largest Australian pathology laboratory reference interval; monocytes 0.0–1.0 x10^9/L.
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: investigate for chronic infection, autoimmune conditions, or myeloproliferative disorders, monocytes are the precursor to tissue macrophages. Elevation reflects chronic immune activation. Interpretation and an action plan should always involve your doctor.
Monocytes (abs) 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.
