High-Sensitivity CRP
Low-grade vascular inflammation marker that refines cardiovascular risk beyond lipids alone.
Blood draw
24 hrs
Physician-reviewed
What this panel measures
- hs-CRP — low-grade inflammation in the blood vessel walls
- Measured at concentrations 10x more sensitive than a standard CRP
Why providers order it
- Refining cardiovascular risk when cholesterol numbers alone are ambiguous
- A family history of heart disease with normal lipids
- Monitoring the inflammatory impact of lifestyle changes
- Investigating chronic low-grade inflammatory states
No fasting is required. Avoid strenuous exercise the day before — hard workouts can temporarily raise CRP.
High-Sensitivity CRP: frequently asked questions
What does a high hs-CRP mean?
It signals elevated low-grade inflammation, which contributes to artery damage over time. A single high reading can come from a recent infection or injury, so providers usually confirm with a repeat test two or more weeks later.
What is the difference between CRP and hs-CRP?
They measure the same protein, but hs-CRP detects far lower concentrations — the range relevant to cardiovascular risk rather than active infection.
Can hs-CRP detect a heart attack?
No. It is a long-term risk marker, not an acute-event test. It helps estimate your risk over years, not diagnose what is happening right now.
Often ordered together
Advanced Lipid Panel + ApoB
Beyond standard cholesterol: particle counts and ApoB for true cardiovascular risk stratification.
Homocysteine
Amino-acid metabolite tied to B-vitamin status, vascular health, and methylation efficiency.
