CRP (standard): what your result means.

Standard C-reactive protein; a general marker of infection or inflammation. CRP (standard) is measured by blood test as part of the Inflammation panel in the HodieLabs Health Blueprint.

Why CRP (standard) matters

For cardiovascular risk stratification, hs-CRP (high-sensitivity assay) is preferred over standard CRP. hs-CRP <1 / 1–3 / >3 mg/L stratification is the standard ACC/AHA cardiovascular risk framework.

Associated risks when out of range: Non-specific acute phase reactant elevated in infection, trauma, and autoimmune conditions. Standard CRP is less sensitive than hs-CRP for detecting low-grade chronic inflammation.

Evidence basis

The HodieLabs Evidence-Based Clinical Library classifies CRP (standard) 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 ACC/AHA 2019 primary prevention guidelines; hs-CRP <1 mg/L low risk, 1–3 mg/L intermediate, >3 mg/L high cardiovascular risk. >10 mg/L usually reflects acute inflammation, not chronic CVD risk. 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 CRP (standard) against published clinical authority standards, never arbitrary "optimal" ranges. Measured in mg/L:

Clinical interpretation

• For cardiovascular risk stratification, hs-CRP (high-sensitivity assay) is preferred over standard CRP.
• hs-CRP <1 / 1–3 / >3 mg/L stratification is the standard ACC/AHA cardiovascular risk framework.
• Values >10 mg/L typically indicate acute infection or inflammation and should be repeated after resolution before interpreting as chronic cardiovascular risk.

What improves it: the evidence-based levers

• Use standard CRP for monitoring acute inflammation; use hs-CRP for cardiovascular risk screening
• CRP >10 mg/L suggests acute infection or significant inflammation requiring investigation

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

How CRP (standard) testing works at HodieLabs

CRP (standard) 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.
