About this test

The High-Sensitivity C-Reactive Protein (hs-CRP) test measures very low levels of C-reactive protein in the blood to detect subtle, ongoing inflammation. Unlike standard CRP tests that identify moderate to severe inflammation, the hs-CRP test is designed to detect low-grade inflammation that may otherwise go unnoticed.

Low-level inflammation plays a critical role in the development of cardiovascular disease. Even when cholesterol and blood pressure appear normal, elevated hs-CRP levels can indicate increased risk for heart attack, stroke, and other cardiovascular events. This makes the hs-CRP test an important tool for early risk assessment and prevention.

Hs-CRP levels rise in response to inflammatory activity in blood vessels, often years before symptoms develop. By identifying inflammation early, this test supports proactive lifestyle changes and medical interventions aimed at reducing long-term cardiovascular risk.

This test is commonly used alongside lipid panels and other heart health markers to provide a more complete picture of cardiovascular and inflammatory status. When tracked over time, hs-CRP can help monitor how effectively treatments or lifestyle changes are lowering inflammation.

What Is Included In This Test?

This test measures high-sensitivity C-reactive protein levels in your blood to assess low-grade inflammation associated with cardiovascular risk.

Your results can help:

Evaluate risk for heart disease and stroke
Detect chronic, low-level inflammation
Support early cardiovascular risk stratification
Monitor the effectiveness of lifestyle or treatment changes
Provide additional insight beyond cholesterol testing

Results are typically categorized into low, moderate, or high cardiovascular risk based on hs-CRP levels.

Who Should Consider This Test?

This test is ideal for individuals who want a deeper assessment of heart health and inflammatory risk.

You should consider this test if you:

Want to evaluate cardiovascular risk beyond standard cholesterol tests
Have a family history of heart disease or stroke
Have metabolic risk factors such as obesity or insulin resistance
Are monitoring the impact of lifestyle or medication changes
Want early insight into inflammation before symptoms appear

Early detection allows for targeted prevention and more informed health decisions.

What makes hs-CRP different from a standard CRP test?

The hs-CRP test is designed to detect low-grade inflammation associated with heart disease, while the standard CRP test (opens in a new tab) detects moderate to severe inflammation from infection or injury.

Why is low-level inflammation important?

Chronic, low-grade inflammation can damage blood vessels over time and increase the risk of heart attack and stroke, even in people without symptoms.

Will anyone see my results besides me?

Your results are stored in your secure online account. They are not shared with anyone else. If you choose, you can print or download them to share with your own doctor.

Do I need to fast before this test?

Fasting is not required for this panel. You can eat and drink normally unless your doctor has given you other instructions.

Can I talk to someone about my results?

Yes. If your results come back abnormal or if you simply have questions, our team is here to support you. You can text our Patient Services team at 1800-579-3914, anytime between 8am and 8pm.

Can I use insurance to pay for this test?
