C-Reactive Protein (High Sensitivity) (hs-CRP)
Marker of systemic inflammation. The high-sensitivity test predicts cardiovascular risk independent of cholesterol.
Typical normal range
< 1.0 (low risk) · 1.0–3.0 (moderate risk) mg/L
If high ↑
Infection, autoimmune disease, cardiovascular risk, metabolic syndrome
If low ↓
Favorable: low inflammation state
What is a normal C-Reactive Protein (High Sensitivity) level?
A typical reference range is < 1.0 (low risk) · 1.0–3.0 (moderate risk) mg/L. Ranges vary between laboratories and can depend on age and sex, so compare your result with the range printed on your own report.
What does a high C-Reactive Protein (High Sensitivity) level mean?
Infection, autoimmune disease, cardiovascular risk, metabolic syndrome. A single result rarely gives a diagnosis on its own; your doctor will interpret it alongside your symptoms and other tests.
What does a low C-Reactive Protein (High Sensitivity) level mean?
Favorable: low inflammation state. Your doctor will interpret it alongside your symptoms and other tests.
About the Inflammation & Cardiac
Inflammation markers rise when the body is fighting infection, injury or long-term inflammation. Cardiac markers are released when the heart is strained or damaged, and help doctors assess heart conditions.
