What it measures
C-reactive protein is made by the liver and rises with inflammation. The high-sensitivity version can detect lower levels used in cardiovascular risk context, but it does not identify the cause of inflammation.
How it is measured
Blood test. hs-CRP is a more sensitive assay than standard CRP.
What it is useful for
- Adding inflammation context to cardiovascular risk assessment.
- Noticing persistent inflammatory burden that deserves clinical follow-up.
- Separating chronic trends from acute illness, injury, or infection.
How to interpret it
It is nonspecific
hs-CRP can rise from infection, injury, autoimmune activity, intense training, poor sleep, obesity, smoking, and many other causes.
Repeat testing matters
Because acute illness can spike CRP, clinicians often repeat an elevated result when someone is well before treating it as a chronic signal.
Use it with risk context
hs-CRP can support cardiovascular risk discussion, but it should not replace blood pressure, lipids, glucose markers, family history, or symptoms.
What can move the signal
- Treat acute or chronic inflammatory conditions with clinician guidance.
- Stop smoking and reduce excess alcohol exposure.
- Improve sleep, body composition, cardiorespiratory fitness, and dietary quality.
- Avoid testing immediately after infection, injury, or unusually hard training unless directed.
Important cautions
- hs-CRP does not show where inflammation is coming from.
- A high value should be interpreted with symptoms and medical history.
- Do not use hs-CRP alone to decide whether to take anti-inflammatory medication.
Use this inside a system
A biomarker becomes useful when it connects to a decision: retest timing, training load, nutrition changes, sleep quality, medication discussion, or clinical follow-up. Aeonvera is built to place each signal in context with your labs, wearables, protocols, and physician-ready notes.
