Overview of the C-Reactive Protein (High Sensitivity)
he C-Reactive Protein (High Sensitivity) blood test measures low concentrations of C-reactive protein using a high-sensitivity laboratory assay.
The test contains 1 biomarker: High Sensitivity C-Reactive.
CRP is an acute-phase protein produced predominantly by the liver in response to inflammatory signalling.
Standard CRP and high-sensitivity CRP measure the same protein, but the hsCRP method is designed to quantify much lower concentrations accurately.
This makes hsCRP useful in selected cardiovascular risk assessments, where persistent low-grade inflammation may provide additional prognostic information alongside established risk factors.
hsCRP is not a specific test for heart disease.
Levels can increase because of infection, inflammatory disease, obesity, smoking, injury, recent surgery and strenuous exercise.
For cardiovascular-risk assessment, testing is most meaningful when a person is clinically stable and does not have an obvious acute infection or inflammatory flare.
The result should be interpreted alongside cholesterol, blood pressure, diabetes status, smoking history, family history and other cardiovascular markers where appropriate.
What Does the C-Reactive Protein (High Sensitivity) Test Check?
This test measures 1 biomarker.
High Sensitivity C-Reactive
Measures very low concentrations of C-reactive protein, providing a sensitive marker of systemic inflammation that can contribute to cardiovascular risk assessment in clinically stable individuals.
Who May Benefit From the C-Reactive Protein (High Sensitivity) Test?
hsCRP may provide additional information where low-grade inflammatory activity is relevant to cardiovascular or metabolic assessment.
People undergoing cardiovascular risk assessment - hsCRP can provide additional prognostic information alongside conventional cardiovascular risk factors.
People with a strong family history of cardiovascular disease - Additional markers may be considered where inherited risk appears important.
People with borderline cardiovascular risk - hsCRP may occasionally help refine risk assessment when treatment decisions remain uncertain.
People with insulin resistance or metabolic syndrome - These conditions can be associated with chronic low-grade inflammation.
People with obesity - Adipose tissue can contribute to increased inflammatory signalling and higher hsCRP.
People monitoring cardiovascular lifestyle changes - Repeat testing may show whether low-grade inflammatory activity changes over time.
People with a previous unexpectedly raised hsCRP - Repeat testing when clinically well may clarify whether an elevation was temporary.
People having advanced cardiovascular blood testing - hsCRP may complement lipid markers such as ApoB and Lipoprotein(a).
How to Prepare
A high hsCRP result obtained during an acute infection should not be interpreted as evidence of increased cardiovascular inflammatory risk without considering the illness.
Persistent low-level elevations are most meaningful when confirmed under stable clinical conditions.
Symptoms and Reasons to Consider the C-Reactive Protein (High Sensitivity) Test
hsCRP is primarily a risk and inflammation marker rather than a test triggered by one specific symptom pattern.
No symptoms but increased cardiovascular risk - Atherosclerosis can develop silently, so hsCRP may sometimes provide supplementary information during preventive risk assessment.
A strong family history of premature heart disease - Additional cardiovascular markers may be considered even when a person feels entirely well.
Previously raised inflammatory markers - Repeat hsCRP under stable conditions may help determine whether low-level inflammation persists.
Metabolic risk factors without obvious symptoms - Insulin resistance, obesity and metabolic syndrome may be associated with higher low-grade inflammation.
Smoking with other cardiovascular risk factors - Smoking contributes both to cardiovascular disease and systemic inflammation.
Monitoring after sustained lifestyle changes - Weight loss, smoking cessation and improved metabolic health may affect inflammatory status over time.
An unexpected hsCRP result requiring confirmation - Acute infection, exercise or injury can temporarily raise the marker and may justify repeat testing.
hsCRP does not identify where inflammation is coming from and does not diagnose cardiovascular disease.
If you currently have fever, an acute infection, significant inflammatory illness or recent major injury, hsCRP may not accurately represent stable cardiovascular inflammatory risk.

Understanding Your Results
For cardiovascular-risk assessment, hsCRP has historically been considered using broad categories when the person is clinically stable.
Values below approximately 1 mg/L are generally associated with lower relative cardiovascular inflammatory risk.
Values around 1–3 mg/L are considered intermediate.
Values above approximately 3 mg/L can be associated with greater relative cardiovascular risk.
These categories are not diagnostic thresholds.
A result above approximately 10 mg/L often suggests that an acute inflammatory or infectious process may be influencing the measurement.
In that situation, cardiovascular interpretation is usually deferred until the person has recovered.
hsCRP should always be considered alongside established cardiovascular risk factors.
