High-Sensitivity CRP (hs-CRP) Blood Test

hs-CRP

A sensitive test that measures low levels of C-reactive protein, an inflammation marker associated with cardiovascular disease risk.

High-Sensitivity CRP (hs-CRP) is a blood test that measures very low levels of C-reactive protein, an inflammation marker produced by the liver. Unlike standard CRP tests used for acute infections, hs-CRP detects the low-grade chronic inflammation associated with cardiovascular disease.

Research shows that elevated hs-CRP is an independent predictor of heart attacks, strokes, and cardiovascular death - even in people with normal cholesterol levels. The American Heart Association recognizes hs-CRP as a useful marker for cardiovascular risk assessment.

Chronic inflammation plays a key role in atherosclerosis (plaque buildup in arteries). By measuring hs-CRP alongside traditional risk factors like cholesterol, you get a more complete picture of your cardiovascular health.

What This Test Measures

This test measures C-reactive protein at very low concentrations (high-sensitivity assay). CRP is produced by the liver in response to inflammation throughout the body. The hs-CRP specifically detects the low-grade inflammation associated with cardiovascular risk.

Who Should Consider This Test

Adults assessing cardiovascular risk, people with intermediate heart disease risk (10-20% 10-year risk), those with family history of heart disease, individuals wanting to complement lipid panel results, and anyone monitoring inflammatory conditions.

When to Get Tested

No fasting required. Avoid testing during acute illness, infection, or injury as these cause temporary CRP elevation. Wait 2 weeks after illness for accurate baseline results.

Understanding Your Results

Risk categories: <1.0 mg/L = Lower cardiovascular risk, 1.0-3.0 mg/L = Average risk, >3.0 mg/L = Higher risk. Values >10 mg/L suggest acute inflammation (infection, injury) rather than chronic risk and should be retested.

What to Expect

After placing your order, you'll receive an email from Rupa Health (our lab order partner) within 24 business hours to sign a consent form and schedule your blood draw at a Quest Diagnostics location.

The blood draw typically takes just a few minutes. Results are usually available within 1-2 business days and will appear in your secure Justlabs dashboard.

Our results include reference ranges and easy-to-understand indicators showing whether your values are within normal limits.
