The most abundant white blood cell; first responders to bacterial infection. Neutrophils (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: Low neutrophils (neutropenia) increase infection risk. <1.0 × 10⁹/L is clinically significant. High neutrophils indicate bacterial infection, inflammation, stress response, or corticosteroid use.
The HodieLabs Evidence-Based Clinical Library classifies Neutrophils (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; neutrophils 2.0–8.0 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 Neutrophils (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.
Neutrophils (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.

The most abundant white blood cell; first responders to bacterial infection.
The HodieLabs Evidence-Based Clinical Library optimal range is 2.0–8.0 x10^9/L, based on Aligned with largest Australian pathology laboratory reference interval; neutrophils 2.0–8.0 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: neutropenia: assess medications, autoimmune conditions, and bone marrow function, neutrophilia: investigate for infection, inflammation, or haematological cause. Interpretation and an action plan should always involve your doctor.
Neutrophils (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.
